January 15th Bug-Fixing Build


All of the 202X tutorials are complete, and all of the voice acting has been recorded! But, before I can fully release the tutorial, I need to:

  1. Review the voice acting and request any changes if necessary
  2. Put the voice acting into the game
  3. Implement the tutorial cutscene
  4. Adjust the game’s opening sequence so that the game transitions from Intro Cutscene > Tutorial Cutscene > Tutorial > Info-chan Cutscene > Calendar
  5. Do final testing, confirm that it’s possible to repeat tutorials any number of times and do tutorials in any order without anything breaking.

The animations for the tutorial cutscene aren’t finished yet. If they’re not finished by Feb 1st, I guess I’ll just implement a simple “characters pop between static poses and don’t actually move” cutscene, like the original “Senpai meets Amai” cutscene, and use that as a placeholder until proper animations can be created.

Over the past 2 weeks, a lot of valid suggestions/requests were made and a lot of bugs were reported, so a lot of improvements and fixes were made to the game. To see a list, scroll down past this adorable artwork by Emmaria!

Changes and Improvements

  • If you splash Osana with liquid during her sunbathing event, before she reaches the locker room, there is no reason for her to cancel the event, since she was already planning to go to the locker room to change clothes, anyway. So, from now on, splashing her before she changes into her swimsuit will no longer change her plans to do her Thursday event.
  • Updated the eye textures for a lot of characters who were using the default store-bought “Aoi” eye texture, instead of unique eye textures. (Some of these might get updated again in the future, since pupils are supposed to be black and are not supposed to be too close in color to irises.)
  • Earth’s real-life moon will be in the “Waxing Gibbous” phase during the first week of April in 2025, so the moon that appears onscreen during Osana’s stalker stealth mission has been changed to be a Waxing Gibbous moon.
  • Previously, attempting to change Senpai’s hair color at the Senpai customization screen would combine two colors, preventing the player from achieving the color they actually wanted. This problem has been fixed.
  • Prisoners in your basement will now have their health deteriorate faster if there are corpses the basement with them. The rate of their health deterioration will increase with the number of corpses present.
  • Because there are no collectible cassette tapes to listen to in 1980s Mode (kind of ironic, huh?) I’ve disabled the tape player in the school scene when you’re in 1980s Mode.
  • From now on, when you are playing the game on 1/8 resolution textures, the button prompts that appear during the delinquent combat minigame should be more legible.
  • It would be weird if the magazines in the teahouse didn’t change over the course of 36 years, so the magazines in the teahouse are now different in 1980s Mode.
  • When viewing a student’s “Reputation Chart” in 1980s Mode, the art style of the chart now matches the VCR aesthetic of 1980s Mode.
  • Students now perform a “looking left and right curiously” animation when they are investigating a suspicious noise.
  • Increasing your Biology stat will now cause corpses to spill fewer blood pools upon death.
  • Updated the eye textures for all 1980s Mode rival girls.
  • Updated Kuu Dere’s hair texture.
  • Updated Pippi’s hair model.


  • If the player put a corpse into a garbage bag, put it into the incinerator, did NOT activate the incinerator, and performed the delinquent beat-em-up minigame, the corpse would appear outside of the incinerator, standing up. This bug has been fixed.
  • If a memorial for a deceased student was held at school on a day when Senpai was staying home from school, Senpai’s “aura” would be present in the school gym in the spot that he would normally be standing in. This bug has been fixed.
  • Fixed bug that would cause Osana to change her clothing to an outfit she shouldn’t be able to wear on Wednesday if the player stole her phone, put it on her desk, and advanced to lunchtime before Osana found her phone on her desk.
  • Fixed bug that would prevent the game from accurately remembering how many photographs of Senpai were in the player’s possession if the player used a Senpai photo to restore sanity and then got a game over and reset the day.
  • Fixed bug that would cause the player to spin in circles during the “push student off of rooftop” animation if the player activated the animation while the student was reacting to a camera pointed at them.
  • Fixed bug that would cause faculty members to subtract from your reputation if you pointed a camera at them for too long. (Faculty members shouldn’t do this, because they don’t gossip, like students do.)
  • Fixed bug that would cause Osana to teleport out of her classroom on Wednesday if the player stole her phone, put it on her desk, and advanced to lunchtime before Osana found her phone on her desk.
  • If the player saved and loaded the game after poisoning Osana, Osana would forget that she was supposed to be poisoned, and would restart an event from earlier in the day. This bug has been fixed.
  • If the player attended class while a teacher was holding a weapon and bringing it to the faculty room, the teacher would still be holding the weapon after teaching class. This bug has been fixed.
  • If the player saved the game while wearing a blood-stained painter’s smock and then loaded the save, the protagonist would be wearing a towel when the save was loaded. This bug has been fixed.
  • If the player saved the game with a weapon in their inventory, and then loaded the save, the protagonist would automatically equip the weapon upon loading the save. This bug has been fixed.
  • Fixed bug that would prevent a teacher from responding properly to the player if the player attempted to report blood/corpses to a teacher while another student was doing the same thing.
  • Fixed bug that would cause Senpai and Osana to appear as blue and pink silhouettes if the player had the “low-detail students” graphical setting enabled from the start of the school day.
  • Fixed bug would cause Raibaru to forget about being electrocuted and spy on Osana if Osana’s Monday phone event activated while Raibaru was in the process of being electrocuted.
  • Fixed bug that would cause Sonoko to enter the “reacting to Ryoba running nearby” state while she was meant to be running to a meeting location to have a meeting with someone.
  • There was a bug that would cause the “Tripwire Checklist” to appear onscreen even if there was a wall between the player and the water cooler. This bug has been fixed.
  • Fixed bug that would cause a corpse to teleport a few meters to the side if it was dropped in a very specific spot in the girls’ shower building.
  • Fixed bug that would cause Kyuji to slide across the ground if the player distracted him with a giggle while he was on his way to gaze at Osana.
  • Security cameras will no longer consider you “suspicious” when you’re splattered with blood if you’re wearing a painter’s smock at the time.
  • Fixed bug that prevented the game from updating the text on the Stats screen to say “Newspaper” when the player joined the Newspaper Club.
  • Fixed bug that would let the player clip into characters by aiming their smartphone camera at a character while walking towards them.
  • Fixed bug that would cause the game to incorrectly count the amount of bloody clothing at school if a painter’s smock became bloody.
  • Fixed bug that prevented the Stats screen from displaying the player’s club if the player checked the Stats screen while at home.
  • Fixed bug that would cause a 1980s bookbag to appear at Osana’s desk if the player performed the delinquent beat-em-up minigame.
  • Fixed bug that would prevent Chigusa from using the “cuddle with boyfriend” routine if she was eliminated through matchmaking.
  • Reverted rendering change, since it caused the ends of hallways to flicker when viewed from the opposite end of the hallways.
  • Fixed bug that allowed the player to save up to 26 photographs, even though the Photo Gallery can only hold 25 photographs.
  • Fixed bug that was preventing the player from suffering a reputation penalty after being caught lockpicking or stealing.
  • Fixed bug that allowed the player to interact with things while the game was paused during the asylum stealth mission.
  • Fixed bug that would cause characters to ignore misbehavior for the rest of the day after being hit by a stink bomb.
  • Fixed bug that would cause the 1980s Mode confession music to play in 202X when a suitor confessed to a rival.
  • Fixed rendering bug that prevented the game’s mirrors from properly rendering the environment nearby them.
  • Fixed bug that allowed the player to use the cinematic camera without enabling Debug commands.
  • Fixed skinning/clipping issues with the long skirts of the female delinquents in 1980s Mode.
  • Fixed bug that would screw up Raibaru’s pathfinding if the player spoke to Osana.
  • Fixed a typo in one of Teiko’s subtitles.

That’s It?

I feel like I had tremendous momentum in the 2nd half of 2022, but I feel like my momentum really slowed down in late December and early January. I feel really guilty about that. In fact, I feel so bad about my lack of progress lately that I “banned” myself from streaming video games on my Twitch stream until I feel that I’ve returned to my previous levels of productivity.

It’s easy to see where the time went in early January, though:

All of these things took a lot of time away from development, but are things I really wanted to take care of at the beginning of the year.

In addition to that stuff, there were also a couple of other things that took my time, focus, and attention away from the game over the past 2 weeks…

  • Two of my hard drives died, and I had to restore from recent backups
  • My roof developed a leak, allowing rainwater to damage part of my ceiling, and both the roof and ceiling had to be repaired

Both issues have been taken care of, but man, those sorts of thing are like black holes that just suck up your time. There was also some other stuff that robbed me of a lot of time in early January, but I’m not going to bother trauma-dumping a bunch of stuff you don’t care about here in this blog post.

Now that all of those blog posts are finished and those hard drive / roof problems have been resolved, I can hopefully return 100% of my focus to game development and make some awesome kickass progress over the next 2 weeks! I anticipate that the tutorial will be totally complete (except for cutscene) by Feb 1st, unless more unexpected problems pop up and steal my focus away from the game.

Now, I acknowledge that this is going to be a really weird thing to say immediately after saying, “I banned myself from streaming games, and I’m going to focus 100% of my attention on game development now!” but…

Steam Anniversary

On January 17th, 2009, I streamed a video game for the first time. It completely changed my life; once I experienced the thrill of playing video games while interacting with an audience, I didn’t want to do anything else! For a period of several years, I streamed every day, usually for 12 hours straight!

In commemoration of that life-changing day, I have an annual tradition: every year, during the month of January, I take two days off from work to celebrate the anniversary of my first video game stream by replaying the first two games I ever streamed. On January 17th, I play Resident Evil 4, and on January 19th, I play Mystical Ninja Starring Goemon.

Even though I’ve “banned” myself from streaming for a while, I refuse to give up my yearly anniversary streams; that tradition is just too important to me. So, on Jan 17th and Jan 19th, you’ll be able to find me streaming RE4 and Goemon on my Twitch channel.

If you’d like to join me, you can find me at twitch.tv/yanderedev. I plan to start at 12:00 noon in the PST timezone, but the stream might start later than that.

Even if you only pop in for a few minutes just to say hello, I would be very happy to see you there!

  1. Oh that’s cool! I’m so happy that the tutorial is coming very soon! I have a few questions though!!

    So i was reading the yandere simulator wiki, and I stumbled across Taeko Yamada’s page and it got me thinking… Are we going to get a female senpai when the crowdfunding campaign happens? I sure hope so. The Art Mulberry made for Ayano and Taeko is adorbs ❤

    and another question is, I was watching your Q&A videos on your archive channel, and I was wondering, without spoiling anything, is there going to be a canon ending? Or is any ending you choose going to be canon, since you are in full control what Ayano does? I wonder….

    • I would like to allow the player to choose the gender of their Senpai, but in order to implement a female Senpai, I would need to pay a voice actress to record female versions of Senpai’s voice lines, and I would need to pay an animator to create female versions of Senpai’s animations. That would be hundreds of voice lines and hundreds of animations, which would probably cost thousands of dollars. So, I would only be able to implement a female Senpai if Yandere Simulator’s upcoming crowdfunding campaign is a massive success and raises an extra large sum of money.

      And yeah, there will be a “canon ending” for Yandere Sim.

      • I’d like to be the female senpai’s voice actress, but I’m underage, I don’t know if I can do it. I’d be happy to help out on the rivals’ voices as well. It should be noted that I would do it for free

      • Hello! Yandere dev I’d like to report a bug.
        1. Wear the raincoat.
        2. Go to the art club to get the masking tape and the box cutter.
        3. Seal the box next to the incinerator and insert the box cutter
        4. Drop the box inserted with the box cutter and remove the rain coat by pressing 1 key
        5. The box cutter automatically detaches from the box and it’s unpickable anymore. I tried to pick it up so many times but it didn’t work so I had to restart and delete my progress:(, so could you please fix this bug? Btw this was January 15th built.

  2. I honestly see a LOT of players including myself reporting things to teachers to fast forward time in Yandere Simulator. to the police investigation cutscene. It would honestly make so much sense if you could “comfort” a character currently mourning the death of another character like Raibaru and Osana or the Basu sisters to fast forward time.
    This is just for the sake of convenience, of course.

    Thanks for another update, though, Yandev! They’re always fun to read!

    • The player already has two options to advance forward to police investigation (attend class or talk to teacher), so I don’t really feel that the player needs a third, extremely contextual option.

      • Hello! Yandere dev I’d like to report a bug.
        1. Wear the raincoat.
        2. Go to the art club to get the masking tape and the box cutter.

    • I think the players can comfort the stuednts who witnessed their sibling/best friend’s corpse in the next day, and you can get some reputation after comforting a traumatized student.
      Also, it’d be great if a student change their idle/walking animations after witnessing a corpse, just like the rich girls who got ransomed in the 1980s mode.

  3. Uhmm… the “Direct download from the official website” option has the wrong build in it (january 1st) [latest.zip] ~

  4. I couldn’t wait for the tutorial tho! I am a player of this game for 7 years and I pretty much know everything but my Sister which I introduced this game haven’t known how to play and get away with murder so I think it’s cool that a tutorial will be on place!

  5. My family just had a roof problem fixed too, so I know how time consuming that can be.
    Sorry to hear about your hardrives tho dev.
    I feel pained just thinking about it. I have to basically reset my computer every few months because of a bug with windows 10, so I know the pain of having to move things to an external drive and redownload other things I need. (Not to mention the one time I deleted something on that drive to free up space that I had forgotten to transfer to my computer after the reset and I had to spend hours getting it all back.)

    No worries if you haven’t had as much motivation. Happens to the best of us; I myself am a frequent procrastinator because of how easy it is for me to lose motivation on things.

    I saw another comment mention something like a system to implement mourning and it reminded me of the time we had a “Fake reaction” button in the yandere vision menu.
    (I remember that one was removed because of the bugs it spawned with teachers thinking you murdered someone with no other evidence.)

    • I agree! I’m also like you, I lose motivation to do things pretty easily too… so I know how YanDev must have felt. it’s so amazing how he could work on the same thing for years and still doesn’t lost his motivation! My respect for him is growing every day!

    • I don’t think the Yakuza ending will be added to 1980’s mode because creating an ending like that will take a lot of work and time… but who knows?

      • In the final scene, instead of the journalist, the yakuza arrives, gives you a test (do the beat em up mini-game again) and if you succeed you win the final “Y”.

  6. I think I found a bug. When I put a bloody weapon in the Light Music Club cello case and drop it in front of a student, they will say, “Huh? What is that?” and instead of walking towards to investigate it, they don’t do anything and say “Uh, okay then”.

  7. Oh wow, I’m so excited to see the new tutorial! great job on all the fixes and changes, YanDev! I love the fact that Prisoners in your basement will now have their health deteriorate faster if there are corpses the basement with them, the detail in this game is so amazing! and the moon too, wow!

      • True, I agree. Yandere Simulator is too easy right now because of all the OP mechanics like kidnapping. so making the prisoners get much hungrier if they’re nearby corpses and having to feed them frequently will make the game more balanced and fun.

  8. I wish we could see the Journalist instead of Megami after beating the Alphabet Killer Challenge in 1980s Mode. Since Megami is not supposed to be in the eighties…

      • I still have a bug to report:1.If the rival likes bandana which the suitor wears, The matchmaking result is “Your rival loves her suitor’s pierecing!”
        2.If you read manga during the day, you skip straight to Monday instead of Sunday night. It doesn’t make sense because going to the Maid Cafe or taking a break skips to Sunday night.
        3.If I choose to start a certain week directly in 1980S, after starting the game, the display of statistics (Stats) for this week’s rivals will be:
        “Efforts are still needed to eradicate the cause of death is considered murder. (Not eliminated yet Belived to be murdered)”
        The correct one should be: “We still need to work hard to eradicate it. The end is undecided. (Not eliminated yet No detail to provide yet.)”

  9. Don’t feel pressured to give up such a precious tradition YandereDev. Consider it one of your many rewards for another year of hard work and maybe even practice for a streaming career once Yandere Sim is done

  10. Will there be a posibility that all rivals are on the “orientation/tutorial” day since technically they were on school before week 1 of gameplay?

  11. Dear Yandere Dev, I’ve been going over the “Pre-Crowdfunding Checklist” and after reading through it I think I can recommend that you should go over the ones that I think are the easiest before heading doing the hard part:

    1.Add a tutorial to 202X Mode
    2.Allow the player to adjust the game’s resolution from the Settings screen
    3.Allow the player to read manga while at school
    4.Give functionality to the two remaining demons
    5.Implement an “aiming” state
    6.Implement voice lines for the 1980s delinquent boys
    7.Replace modern-day models that appear within 1980s Mode
    8.Implement 5 generic tasks

    The rest are the hard parts.

    Also, side note, I think the “aiming” state should be more akin like “Resident evil 4” or “Bully”

    • You should read the blog posts. Your #1 is closer than you think!

      Also I have to agree with the others, not to come at you or anything, dear me no. It is never my intention to be abrasive or dog pile on people.

      I just think we should let YanDev get to developing things in his own time. He is a human being with needs and a life. It will be ready when it’s ready. So let’s all have fun~! 👍🏻✨

    • I disagree, because I think YanDev should focus on the big, important parts of the game first before adding all the small changes. but that’s just my opinion. As the people above me said, it’s YanDev’s choice. he’s the developer of this game after all.

  12. Nice Update!

    I have a question regarding the alerts system though,
    The game tallies how many times the player has alerted someone with suspicious activity, but if you kill the person that saw you do something suspicious in the same day, shouldn’t that negate the alert? Because you got rid of the witness before they could tell anybody but the player being caught for a second, despite eliminating the witness, gets penalized at the end of the game when they’re graded about how they preformed. Maybe it’s an intentional thing for players to be more careful but I was just curious if this was an overlooked thing or done on purpose.

    Keep up the great work as always!

    • I’m sorry, I can’t. The screen stops updating (stops displaying any new frames) when the game is loading. This means that I can’t have a loading bar appear that accurately reflects the loading progress.

  13. Hi YanDev! I think I found stg like a mistake but I’m not sure. You can climb onto the chair in the corner where Osana had her conversation with the stalker.

  14. Hey YanDev! I’ve been catching up on Yandere Simulator and I gotta say, I’m so excited for the crowdfunding campaign! I don’t know if I will donate to the crowdfunding campaign but I will definitely get Yandere Simulator once it releases on Steam in early access. Thank you YanDev for creating one of my favorite games of all time and I will be supporting you till the full release of Yandere Simulator or even Yandere Simulator 2 if that became a thing.

  15. yanderedev I would like to report a bug
    in the bush at the entrance to the school there is a bush without a collider and therefore ayano can go through it

  16. Happy Chinese Lunar New Year Yandere Dev. May the water Rabbit signify swift and smooth progress for you this year (:

  17. oh… my problem with the latest hair is that the ponytail is too polished and looks best only in the highest quality and I don’t play it and it doesn’t look good… And as for the fact that with the H code on the keyboard I can change Ayano’s hair for the older ones it’s a bit true because there are those student-chan and Ayano had them and I expect those from before March 2022 that were created in 2021 in November

  18. Hello! I just wanted to notify you yanderedev that I’m pretty sure the sun doesn’t move in the game when time progresses. I’m not sure if it’s due to technical issues, or you forgot simply.

  19. Y’all I’ve just checked the trello page – there are 4 more things remaining to get done and then we have the tutorial =DD yaaaay

  20. One thing I would like perhaps have the mini game in 202X when you’re waiting for time to pass be in the form of one of those free-to-play time killer mobile app games that Ayano might have on her phone, since people nowadays tend to use apps on their phones to pass the time. But I do get that it needs new assists.
