August 15th Bug-Fixing Build

New build! 32 improvements and 38 bug fixes. That means there are a total of 70 differences between this build and the previous build – that’s a lot!

With that said, I think I can already predict what some of the comments are going to say. “No new features? No new content? I’m disappointed!”

Hey, I also wish that I could have spent the past 2 weeks adding new features and content to the game, instead of fixing bugs. But, if a bug gets reported, I can’t just leave it in the game. I have to fix it. As a game developer, I’m not just going to willfully leave bugs in the game if I’m aware that they exist. Fixing things that are broken takes priority over adding new things to the game.

It’s not like I decide, “I choose to fix bugs for the next 2 weeks!” It’s more like, “Sadly, I have to fix a bunch of bugs before I can do the things I actually want to be doing with my time.”

I hate that it’s been like this for about 8 weeks now. I hate that, instead of coming to you with a cool new update that will thrill and excite you, I have to come to you with a bug-fixing build – again. There’s a giant list of things I’d rather be putting into the game, instead of working on bug fixes…but, hey, I can’t just ignore bug reports and leave egregious problems in the game. That would be horrifically irresponsible, and would only have devastating consequences later in development.

The next stage of the game’s development is the crowdfunding phase – the part where I say, “Here, download this free demo, it represents what the final product could be like. Donate if you want the final product to exist!” When we reach that stage, the game absolutely cannot be a buggy broken mess that is full of exploits and oversights, leaving a horrible impression on the player. Who would want to fund that?

Sadly, the fact of the matter is that we’re in the “nothing cool or exciting happens for a few months while I just fix bugs” phase. I bet you’re not happy about that. I’m not happy about that, either. In fact, I hate it. It’s annoying and tedious and boring as hell for me to just fix bugs all summer. But, even if you and I both hate it, it’s still necessary.

I wish it didn’t have to be this way. But it does. I’m not going to ignore bug reports, no matter how desperately you (and I) wish that I was working on something more exciting and interesting.

Every time I upload a new build on the 1st or 15th day of the month, I think to myself, “There! Everything is fixed. No other bugs can possibly remain in the game. The game is flawless. Now I can spend the next 2 weeks putting cool new stuff into the game!” And then, 2 weeks later? “Hey guys, here’s a new build with 38 bug fixes…”

The bug-fixing builds will stop when the bug reports stop. I can’t predict when that’ll happen, but eventually, it’ll happen. And the game will be better off for it.

I mean, think about it – when I finally put more rivals in the game, you don’t want to have bugs and oversights ruining your experience and pissing you off every 5 seconds, right? Well, then. That means I’d better continue what I’ve been doing, and fix all the problems that currently exist in the game.

Well, you know the drill. Fan art, followed by changelog.

Changes and Improvements

  • During Osana’s week, on Friday, the Art Club paints the cherry tree where Osana confesses to Senpai. This is so that there are witnesses nearby Osana while she’s waiting under the tree for Senpai, so that it’s not too easy for the player to simply run up and murder Osana there with no consequences. However, there were several oversights: The female members of the Art Club were not present, the characters’ cones of vision were not large enough to actually see Osana being murdered, and the characters’ vision was blocked by the canvases they were painting on. All of these oversights have been resolved, so that now the Art Club actually reacts and takes action if they witness murder under the cherry tree on Friday.
  • If a student was running to report something suspicious to a teacher – a weapon, a blood pool, a bloody weapon, etc – that student would completely ignore the presence of any corpses while on their way to report the suspicious object, even if they were running through a corridor completely filled with dead bodies. From now on, any student who is running to report something to a teacher will still be able to notice corpses, and will change their priority from “report suspicious object” to “report corpse.”
  • If a student takes an incriminating photo of the player with their phone, and then the player kills that student, the student will drop their phone. This dropped phone can be found by police, who will find the incriminating photo and arrest the player. This outcome can be avoided by crushing the dropped phone under your foot. However, there was a bug that would cause the dropped phone to turn invisible if the player concealed the victim inside of a garbage bag. This bug has been fixed.
  • A Teacher’s Pet reacts to murder by reporting it to a teacher – but if someone else is already reporting the murder, the Pet runs and hides in their classroom, instead. However, if a Teacher’s Pet witnesses murder INSIDE of their classroom WHILE they are hiding inside of it, they should no longer consider their classroom to be a safe hiding place. So, from now on, Teacher’s Pets will run out of school if they witness murder while they are hiding in a classroom.
  • When the player was caught misbehaving by the student council and sent to the counselor, the game would check for the presence of corpses on school grounds, but would not check for bloody weapons on school grounds, or even for bloody weapons in the player’s inventory. This oversight has been fixed; the game now checks for the presence of those things when sending the player to the counselor.
  • The player will now lose sanity while dropping a heavy weight onto someone’s head from above, pushing a sleeping student into the pool, crushing someone with a bookcase, setting someone on fire with a candle/bunsen burner while they are doused with gasoline, electrocuting someone with a thrown car battery, or putting lethal poison into someone’s food.
  • From now on, if a student is hiding in their classroom because they suspect a murderer is at school, they will react negatively when they see the protagonist wearing a raincoat; they’ll immediately jump to the conclusion that the protagonist is planning a murder and is be wearing a raincoat to avoid getting bloody.
  • If the player killed Osana and framed someone else for the crime, the game would incorrectly log her manner of death, so in the “Senpai meets Amai” cutscene, the game would freeze one it gets to the part of the cutscene where Senpai is supposed to explain what happened to Osana. This bug has been fixed.
  • If a student witnesses the player poisoning their bento at lunchtime, that student will refuse to eat their bento. However, if Osana witnessed Ayano poisoning her bento or Senpai’s bento on Monday morning, she would proceed forward with the bento event anyway. This oversight has been corrected.
  • Students now think that it’s weird and annoying if the player repeatedly turns on a loud radio playing obnoxious music. They’ll tolerate it the first time, but if they witness the player doing it more than once, they’ll get annoyed and your reputation will be damaged.
  • From now on, any student at school who does not have a crush on another student will have “None” in their student profile, and if they do have a crush on another student, it will say “Unknown” in their student profile (until the player uncovers who it is).
  • If the player joined the delinquents, then got the delinquents expelled from school, the player would lose the ability to quit the delinquent gang, and would be stuck in the gang, unable to ever join any other club. This bug has been fixed.
  • One of the buttons that is visible at the bottom of the screen in Yandere Vision was greyed out, making it seem as though the button had no functionality, even though the button was indeed functional. This oversight has been fixed.
  • Osana’s “talk with Musume in the plaza on Friday morning” event will no longer occur if Osana is busy looking for her lost phone; she would be too preoccupied with her missing phone to care what Musume wanted to talk about.
  • From now on, if a student is pushed from the rooftop, nearby students will react to the noise that is caused by the student striking the ground or landing in the dumpster, and will walk over to investigate what they heard.
  • From now on, if the player brings a screwdriver from home to school, the “Sabotage a vending machine with a screwdriver” Scheme will skip from Step 1 to Step 2 (no need to find a screwdriver; the player already has one).
  • Students will now find it annoying if you keep giggling in their presence. Giggling more than 5 times while nearby a student will now cause them to react negatively and damage your reputation.
  • Added “Ichirou Saikou graduates from Akademi” to the timeline at the end of the True Ending, since a lot of people presumed that he didn’t graduate because that text wasn’t in the timeline.
  • When using the “teleport to music clubroom” debug command in 1980s Mode, the weapons that spawn inside the music clubroom will no longer clip inside of the tables inside of that room.
  • Removed exploit that made it possible to escape the Journalist by laughing if the Journalist became aware of Ryoba’s murderous actions while Ryoba was laughing.
  • Rivals will no longer agree to follow you at lunchtime, since it’s way too easy to kill a rival by just waiting until lunchtime and asking her to follow you.
  • From now on, if you shove a student from the rooftop, nearby students on the rooftop will hear the scream and walk over to investigate.
  • If a student council member spotted the player misbehaving while guarding a corpse, the game would softlock. This bug has been fixed.
  • The current week is now displayed at the top-right corner of the screen, in addition to the current time, weekday, and phase of day.
  • Students who are set on fire while standing in front of a wall should no longer clip through the wall during their death animation.
  • It is now possible to use Pose Mode to make a girl wear the loose socks of Raibaru and the stockings of Dafuni, Inkyu, or Sakyu.
  • Kidnapping a student will now lower school atmosphere by 90%, because students should be worried if somebody suddenly vanishes.
  • An adjustment has been made that may reduce the loading times when returning from school to the protagonist’s home.
  • Adjusted the color of the pause screens in Mission Mode so that the text should be more legible now.
  • Increased the volume of some of Osana’s voice lines, since they were too quiet.
  • Updated the appearance of the “Nozama” shopping screen.
  • Updated Yui Rio’s hair model.


  • Fixed bug that caused an “invisible” kidnapped victim to be present in Ryoba’s basement if the player kidnapped a rival, turned her into a mind-broken slave, made her kill someone, and then disposed of the slave’s body without anyone knowing that the slave had killed someone at school.
  • Fixed bug that would allow the player to retain control of the protagonist (the ability to run around, aim the camera, etc) if the player took a photograph at the exact moment that they were caught misbehaving by a student council member.
  • Fixed bug that was preventing the game from correctly calculating how much Sanity should be lost when the player performs a murderous action; the game was ignoring whether or not the player was wearing the “sanity panties.”
  • Fixed bug that would cause Raibaru to psychically become away that the player had attacked Osana if the player killed Osana under the cherry tree while Raibaru was on the other side of the map drinking water or something.
  • Fixed bug that would cause the game to softlock if the player pressed the “X” Button (or the “F” key) in the saving/loading menu. (The game was trying to access debug functionality that had been removed a long time ago.)
  • Fixed bug that would cause the delinquent club’s theme (the music that plays when talking to the club leader specifically) to play nonstop and never go away after the player performed the delinquent beat-em-up minigame.
  • Fixed bug that would cause the game to get stuck in an “about to start fight, but the fight never happens” state, if a delinquent dropped his weapon and then the player attacked the delinquent from the front.
  • Fixed bug that would cause Raibaru to sit in midair and eat food in strange locations (the shoe locker area, under a tree in the plaza) if Osana was killed while Raibaru was mentoring the Martial Arts Club.
  • Fixed bug that would prevent Osana from playing the “being stabbed to death by a mind-broken slave” animation if the player was talking to Raibaru at the point in time when the animation was meant to begin.
  • Fixed bug that would cause time to pass at super-high speeds if the player was using the Pass Time ability at the moment in time that a suitor reached the confession tree to talk to the current rival.
  • Fixed bug that would cause the Basu sisters to slide across the ground while performing a sitting animation if the player threw a stink bomb at them during one of their morning conversations.
  • Fixed bug that caused the game to mistakenly believe that a bloody weapon was still present at school after it was incinerated, if that bloody weapon had been held by a mind-broken slave.
  • Fixed bug that would cause Raibaru to become unable to exit her “walk around stretching and exercising” protocol if Osana died during the Tuesday book event while Raibaru wasn’t present.
  • Fixed bug that would cause the “You didn’t allocate any study points!” warning message to appear even if the player had already achieved the maximum rank in all of their school subjects.
  • Fixed bug that caused the “blue tint” post-processing effect to disable itself if the player started a 202X save file, returned to the title screen, then started a 1980s Mode save file.
  • Fixed bug that prevented the game from recognizing that the player had eliminated their rival if the player used the “Internet gossip” mechanic to reduce their rival’s reputation.
  • Fixed bug that prevented the “You are friends with this student” icon from appearing on a student’s icon in the Student Info Menu when viewed inside of the protagonist’s home.
  • Fixed bug in the “Nozama” shopping screen that allowed the player to change the currently-selected product while the “Would you like to purchase this?” window was onscreen.
  • Fixed bug that would allow the player to change their weapon in the middle of an attack animation if a Heroic student was running towards them during the attack animation.
  • Fixed bug that would cause Ryoba to perform a sitting animation without a chair and just sit in midair if she attended the Photography Club’s club activity in 1980s Mode.
  • Fixed bug that would cause certain characters to perform a walking animation while traveling at running speed, while they were moving towards a radio to turn it off.
  • Fixed bug that caused the game to get permanently stuck at the Game Over screen if the player got a Game Over in either the Stalker House or Asylum stealth missions.
  • Fixed bug that caused an “Expelled by Counselor” event to result in a “suspended for 1 day” outcome, instead of the expulsion game over that was intended to happen.
  • Fixed bug that caused the “Push Senpai’s book into the fountain” button prompt to remain in existence even after Osana’s “read book at fountain” event had ended.
  • Fixed bug that would cause visual glitches in Mission Mode if the player started a mission that involved a disguised Nemesis, died, and then retried the mission.
  • Fixed bug that allowed the player to pick up the corpse of a rival without being noticed by Senpai/Raibaru as they were kneeling right next to the rival’s body.
  • Fixed bug that would prevent the game from remembering the player’s preferred framerate cap when returning from the Light Music Club’s rhythm minigame.
  • Fixed bug that would cause the game to freeze at the end of the “Senpai Rejects Osana” cutscene if the police had been called to the school that day.
  • Fixed bug that would cause Osana to glitch out if the player used stink bombs to interrupt her “put two bentos on her desk” event on Monday morning.
  • Fixed bug that would cause corpses to float up into midair after being dropped down into the sewer, if the game was running at a low framerate.
  • Fixed bug that would cause Raibaru to run away from Osana if the player spooked Osana during one of her “talk privately with Raibaru” events.
  • Fixed a bug that would cause the liquid inside of a water cooler to change color to solid white whenever the player used Yandere Vision.
  • Fixed bug that could cause some students to get stuck in the “hiding spot” where you can spy on Osana’s Monday morning phone call.
  • Fixed bug that would cause the game over screen to be blurry if the player reached that screen after being apprehended by Raibaru.
  • Fixed bug that would cause the mouse cursor to display onscreen while in the protagonist’s home or while shopping in town.

  1. To be honest, I feel like it’d be cool if you had a list with all the remaining tasks just like the Osana checklist before the demo was released. You can try doing this but only if you want to of course.

    • tru, he does have one but for now it’s just the bug fixing, how about he moves on to amai once he feels like over 80% of the bugs are gone or bug reports drastically decrease?

  2. Its okay Yanderedev, take your time in fixing the bugs that might happen in the game. i will wait until the full game will be finished! I think it will look super amazing when its finished!

  3. Can you make it as when raibaru sees a mindslave trying to kill osana or anyone else she will stop the mindslave? i think it would be more of a challenge to try beating osana.

  4. When you turn on a radio during class time (when teachers have reached their respective class) to distract a teacher of the classes 1-2, 2-2, 3-2 (doesn’t work with 1-1, 2-1 and 3-1) and kill them with any sharp and spall weapon, the body of the teacher clips into the wall of her class and alerts everyone in that class (not useful for genocide ending :/)
    PS : attack her stealthy while she’s turning the radio off, and the radio must be really close to the class wall

  5. hey, wouldn’t it be cool if the student you asked to distract another student ACTUALLY texted you who their crush was? i mean, its a cool little feature.

  6. I understand the reason you’re focusing on bugs. It’s something I have often communicated to people.

    I have family in the game making industry. I understand the difference between a large scale development team and an indie developer with volunteers. This development time is a normal process for these circumstances.

    I wish you the best and hope you’re having a wonderful day/night wherever you are.

  7. Well even if bug fixes annoy me, this is necessary and I understand what you need to do. Keep up the good work and courage for the future.

  8. There is no need to apologize for the obvious Mr Yanderedev, i am not a game designer/programmer, but i do make programs, and this ¨issue¨ you are warning us about is no issue at all, it is how programming works.
    I will take this time to also inform you that i have been following the development of Yandere Simulator (XD) for many many many years already, and i am eagerly waiting for a chance to participate on a funding campaign. I am not a fan of assassination games (i am more of a fighter pilot), but the whole story of your struggles to develop Yandere Simulator is just epic, and deserves all the help it can get, so i will not only be helping with fundraising, i will buy the final product.

    • Same!! I followed this game for a reallly long time. I will support yandev no matter what happen! I can’t wait for the crowdfunding/final game!!

  9. After reading the patch notes, there is something that really triggered me, the fact that if someone has a crush on someone else, they will just know it (none vs. unknown), i admit that this brings a flood of unpleasant memories from the past, but i still think you should not be giving armor piercing ammunition to your enemies, at least not willingly. Let it be ¨none¨ OR ¨unknown¨ until you discover it.

  10. hello yandere dev I have a question about when the game is finished and the question is if yandere simulator will be paid when it is finished? the question the truth came to me since many fans like us do not have much money to buy the game if it becomes paid that is my question take care yandere dev ❤️

  11. i must say that it became much more realistic on how students react on certain things like the radio one, very nice

  12. Gamers to TripleA Dev’s and studios: We want more transparency for you and to keep your promises!
    Gamers to a developer who’s been transparent and keeping his promises: Why are you talking about bug fixes? Don’t talk to us unless you have cool new stuff!!!

    As a famous Zan-clan man once said: While the modern gaming industry is largely terrible, so are gamers so maybe this is deserved.

    Honestly, you can’t win with gamers

    • Exactly. There’s been many studies dedicated to this. It’s actually entitlement grown from the modern day conveniences of the internet and delivery services.

      Want a free game? Go to the app store. Want some groceries/restaurant food? GrubHub. Want a cute item you saw in the store? Drop shipping! Same day delivery! Want a free funny video? YouTube/TikTok. Want to go somewhere without driving yourself? Uber. Need a map? Google Maps. Need some info? Google it.

      Everything we want is at our fingertips. We have been streamlined into getting what we want and getting it fast. It builds this psychology in people that if it isn’t fast it’s bad. If you have to wait on something it’s bad. People for some reason have a “right” to getting things at a certain time. It builds a disconnect in some people and they forget that this person isn’t a robot there for their convenience.

      • Well said. In fact, what right would we have to complain that the game isn’t fully out yet? It’s free; And we are not the ones working on it at all.

      • Thanks, I am glad to find someone of a similar mindset. I have family in the game making industry. This is a normal development time.

        People don’t realize that even large game companies take this long. You usually don’t get to see the beta testing period and only hear of it when it’s close to completion. The treatment Indie Developer’s face is mind boggling to me. They don’t have huge production teams, animators, huge programming teams, marketers, 3D artists, VAs on speed dial, nor the financial backing of a huge company.

        People like to use the term “development hell” without understanding that the scope of the project determines how long the development period is and if you accompany something large scale with an indie developer then it should be no surprise it takes so long. This is all completely natural and normal.

  13. Hey, Yandere Dev! I’ve been following the development of Yandere Simulator ever since KubzScouts started playing it and I’ve noticed how much it’s been improved but I have a few questions.

    Have you figured out why the FPS is so bad?
    When do you think all the rivals in the game will be implemented?
    How long do you think it will take until they are implemented into the game?
    What are your plans for the game in the future?

    I hope you’re resting, eating and hydrating well. If you could answer these questions, that would be great. If not, that’s fine, thank you for continuing the development of Yandere Simulator <3.

  14. omg, what if when you went to the nurses office, the nurse gets suspicious as to why you are there, and might ask if you want to spend time there – or maybe you could fake having a headache, and that way you can collect headache poison! however you would have to stay there for a period of time

  15. Honestly, I don’t understand why they get angry because only errors were corrected in previous posts😐, if on the contrary, they should find it satisfactory, it’s a good job😁, and also, there may be VERY annoying errors in the video game.

  16. Hello! Have you considered disposable gloves in the home ec room with the trash bags and such? Sometimes you want to do something without fingerprints but don’t necessarily want to join the drama club, or maybe being able to steal things from clubs for a risk of doing so?

  17. About the “Drive Raibaru to killing Osana” thing that you considered from another post. ( I searched everywhere but I couldn’t find when you posted that comment, I just remember you saying that it was an ok idea.)

    I think you should have to gossip about Raibaru until her rep is below -60 and steal Osana’s phone.
    You would have to buy her KaoBook password or something from Info-chan and post gossip about Raibaru.
    After doing that, you would have to show Raibaru the post on your phone.
    Instead of killing her on purpose, I imagine Raibaru putting a note in Osana’s locker and having an argument on the rooftop. Raibaru would get extremely mad, and in the heat of the moment, Raibaru would accidentally push Osana too hard and off of the rooftop. She would then call the cops on herself and turn herself in. I made a little pose mode version if you are interested in seeing that.

    • Raibaru seems to be a bit selfish, though. Know when we lower Osana’s reputation, she’ll be more worried about her own safety than her friend’s well being. She’d probably try to get away from the guilt.

      • While that is true, she probably would at least talk to Osana, and Osana’s anger issues might aggravate Raibaru and make her think Osana is gaslighting her. Osana would probably push, hit, or at least yell at Raibaru for accusing her of beginning the rumors in a heated argument, so Raibaru, along with all the stress she already has from the bullying, would probably push/ hit Osana back.

  18. I’ve encountered many bugs with the ABC challenge, ( students would phase into walls and places i couldn’t get them)

  19. Given most AAA developers release their game as a buggy mess, I’m actually both impressed and approving of your dedication to developing a finished product. It shows you care about giving us a good game, rather than just half-assing it and expecting money.

    • You showed me a picture of a bug, but you didn’t explain what set of actions will cause the bug to occur.

      I can’t fix the bug without knowing the exact circumstances that cause it to happen.

      If you don’t know exactly what causes the bug, then please record a video of yourself triggering the bug. (I need to see the exact moment that the bug occurs, NOT the aftermath of the bug.)

  20. In future game builds I think it would be really cool if groups of students around the school had different conversations every day of the week about their interests, like in 1980’s mode the rainbow boys and girls would have discussions about different things, like this: Girl 1: “How do you guys feel about cats? my parents have been thinking about getting one but I’m not sure if I want to, I’m pretty neutral on them so I want your guy’s opinions” Girl 2: “I love cats! they’re so fluffy and cute and they make amazing companions!” Girl 3: Ugh I hate cats, they’re so mean and always tear everything up! And they always scratch me..” Girl 4: “I don’t really have any big opinions on cats, I’m pretty neutral on them.” I think it would be cool if yan-chan could listen in on those conversations every day and learn things about students in the school, it would make socializing easier and help raise her reputation faster.

    • I think about this a lot. I can visualize exactly how it would look. However, I’m hesitant to include it in the game, because I worry that I wouldn’t be able to get it working as smoothly as it would be expected to work. It’s something I’ll investigate in the next future, and possibly even ask for another programmer’s help with, if I need help making students smoothly transition in/out of the “conversation” state.

  21. yo dev man, it would be cool if you were able to conceal your identity by stealing a mask from the drama club. and they when the mind-broken slave tries to attack a student youll be able to stop it and get rep bonus without being exposed.

  22. me whom wants to help you but too useless and will break everything be like screaming rn
    and i think you’ve did your best up till now
    i mean its amazing that you did all of that 32 improvements and 38 bug fixed damn bro- whom in the world can finnish them all in 2-8 weeks only you dats really amazing
    imma go download yandere sim for the 99th time-

  23. I think the purposeful eavesdropping is a good idea. Or, perhaps, you could have an “eavesdrop zone,” where you would be in a semi-cutscene mode. When you get near 2 characters having a conversation, the HUD could disappear, and the speech bubbles could appear where a HUD element was. When the player ventures too far from the conversation, the HUD returns, and you are no longer able to see the speech bubbles. Perhaps this even makes sense. If Ayano is listening intently to someone’s conversation, she’s not paying attention to, say, info-chan’s scheme, or the school map, or the time.
