New Build, New Video

EDIT: That was fast! The problems that are described in the video below have already been solved. Read this blog post to learn about the current state of the chat interaction feature!

Early in the game’s development, I frequently set milestone goals for myself. My goals were always the same: to include a new major feature in the game by the 1st or 15th day of every month. I stuck to this system for a long time, until it became impossible (because my tasks became very complex and required more than 2 weeks of work to complete).

At this point in time, I am focusing on fixing bugs, removing exploits, balancing gameplay, and making improvements/additions to the game based on user feedback, rather than hitting specific milestone goals. But, with that said, I still feel guilty and apologetic whenever we reach the 1st or 15th day of the month, and I don’t have a new “major feature” to show off.

In the final days of May, I worked on a feature that I was really excited about – something that I had been dreaming of including in the game for many years. It looked like it was going to be finished by June 1st, too. This made me so excited! It was going to be just like the good old days, back when every build had a “star attraction”, a major feature that people could get excited about.

I added the feature to the game, tested it, confirmed that it functioned exactly as I imagined it…but then, I ran into a problem. A problem that I can’t solve my own; a problem that I’d need another programmer’s assistance to fix.

Ah! So disappointing! It really hurts to be on the verge of releasing something really exciting, and then have to postpone it until I find someone to help me fix a problem that is outside my area of expertise…

Working on that feature and not being able to release it makes me feel like I’m coming to you “empty-handed” today; coming to you with no proof that I’ve been spending my time working on something cool and exciting for you to enjoy. I don’t want that to be the case, so I decided to record a video showing you the progress I made with this feature, even if it’s not ready to be used just yet.

…however, it’s kind of awkward to make a video announcing that I don’t have a cool new feature to reveal, so I don’t want to upload this video to my main channel. Instead, I’ve uploaded it to my secondary channel. Here, take a look:

Aside from that, today’s build also contains a bunch of improvements and bug fixes! Click “Continue Reading” to see a list.


  • The player is no longer able to send a stink bomb to the guidance counselor’s office or Info-chan’s room. (The guidance counselor is too professional to abandon her duties because of a bad smell, and Info-chan has hacked the ventilation system and made it impossible to send any gases into her room. She did this for a specific reason, but it will be one of the last things you ever learn about the game’s lore.)
  • The player is no longer allowed to take off a swimsuit that was splattered with blood until they have showered and removed the blood on it, because the act of doing so could result in the player entering a state where they are “soft-locked” and trapped within the locker room, unable to exit because there is no clean clothing they can put on.
  • Using the ventilation system to send a bad smell into the Headmaster’s office will cause him to leave school and not come back until after lunchtime has ended. (If you send a bad smell into his office after lunchtime, he’ll go home for the rest of the day.)
  • From now on, when students are walking around the school and collecting trash bags to throw away, males will not enter female bathrooms to search for trash bags, and females will not enter male bathrooms to search for trash bags.
  • The ventilation system is now accessed by using the B button instead of the A button, since using the A button could cause the player to accidentally throw a stink bomb instead of accessing the ventilation system.
  • The player is now allowed to kill students while wearing a swimsuit even if there are no clean outfits at school to change into, since blood can always be cleaned off of a swimsuit without disposing of it.
  • Updated the hair model of the foreign boy in the 1980s Mode student council to look less basic/generic and more like the “dreamy foreign boy” character he is supposed to represent.
  • Tweaked the 1989 “Pool’s Closed” artwork to more accurately reflect the student council president’s hairstyle.
  • Several male hair models have been replaced. If you don’t like them, you are welcome to model your own versions and show me screenshots. If I like your models better than the ones in the game, I’ll consider replacing the current models with your models.


  • Fixed bug that would trick the game into thinking that there were bloody weapons present on school grounds even though the player had incinerated all bloody weapons, if the player dismembered a corpse with a circular saw that was not bloody before the dismemberment animation began.
  • Fixed bug that would cause a faculty member to slide across the ground instead of perform their walking animation if they were distracted by a radio after having sent the player to the guidance counselor earlier in the day.
  • Fixed bug that caused the game to permanently mark a save file as being in the Alphabet Killer Challenge if the player activated the challenge and then exited it using the pause screen “return to title screen” feature.
  • Fixed bug that caused the “low-sanity chromatic abberation” effect to remain onscreen when the player returned home from school if the player didn’t restore their lost sanity before ending the day.
  • Fixed bug that prevented the Martial Arts Club from going about their daily routine if the player enabled the “Disable Distance Animations” feature and then never walked anywhere near the MA Club.
  • Fixed bug that would cause student council members to stop acknowledging some of the player’s behavior if they were distracted by the player while returning a dropped object where it belonged.
  • Fixed bug that would cause the “Raibaru counters Ayano’s attack and snaps Ayano’s arm” animation to play without sound if the player rapidly attacked Raibaru immediately after killing Osana.
  • Fixed bug that would cause the game to incorrectly remember the number of bloody uniforms at school when reloading a save that was made while the protagonist was wearing bloody clothing.
  • Fixed bug that would cause students to forget what they were doing if they were distracted by the player aiming a camera at them while they were taking a garbage bag to the incinerator.
  • Fixed bug that would cause characters to slide across the ground without a walk animation if they were distracted by the player while returning a dropped object to its proper location.
  • Fixed bug that caused a random number of dumbells to disappear from existence after being placed inside of a bucket and used to crush a student’s head from the rooftop.
  • Fixed bug that would cause the game to incorrectly remember the player’s chosen school uniform when using the “Reset Week” feature on the Calendar screen.
  • Fixed bug that would cause a student to sunbathe in the incorrect location if they were fed by a Cooking Club member while in the middle of sunbathing.
  • Fixed bug that would cause the game to count a body part hidden inside of a bookbag as an unconcealed body part when attempting to attend class.
  • Fixed bug that would cause the student council to perpetually ignore giggles if they shoved the player away while investigating a giggle.
  • Fixing bug that would cause students to spawn wearing the wrong shoes or turn white while changing shoes if the player reloaded a save.
  • Fixed bug that would cause two photographs of Ritsuko to appear during her memorial if the player saved and loaded after killing her.
  • Fixed bug that would cause the game to forget whether or not a weapon should be splattered with blood upon reloading a save.
  • Fixed bug that would cause Ryoba’s gym uniform to turn pure white if she changed into the uniform after reloading a save.
  • Fixed some errors with the 1980s Mode female delinquent hair models.
  • Fixed typo on the ventilation system screen.

  1. This encourages streaming the game on YouTube. It’s only giving the game more opportunities to be noticed and grow.

    • Even if I don’t think this new feature makes the game better, now is the right time to add something like this – it will help more people see the game in its almost completed state, which means it will increase the chances of a successful crowdfunding campaign.

  2. I like the idea to add more streaming attraction to the game. That’s so lame Twitch didn’t remove their ban to the game. The game evolved a lot since 2014.
    Is the game better or worst than you had the first ideas when you imagined the concept of a ”killer psychopath emotionless school girl in love with a guy but she cannot tell her love” game? (This question is pretty much bad written I know)

  3. It would be for superchat, so that streamers would be more likely to play yandere simulator, in short. It’s a marketing thing.

    But if you don’t stream, the feature won’t affect your game in any way. Yanderedev is a streamer, so it makes sense he’d want to make a feature like this.

  4. I’d try making it run in a different thread. That way it’s independent of the game and doesn’t slow it down.

  5. When I’m playing the ABC challenge, sometimes the boys spawn at the fountain instead of their clubs(like the Art Club leader should spawn inside the Art Club) but the girls always spawning inside their clubs
    If they spawn in the fountain, I have to wait until the sports club leader walks to the boys’ locker room slowly in order to join the club! What a waste of time!
    I think it’s related to the code… Is there any way to fix it?

    • I’m sorry, I can’t reproduce this bug. I can’t reproduce any bug where the instructions to reproduce the bug are “sometimes it happens.” I need to know specifically what exact circumstances cause it to happen.




  7. This game is really coming together. Even though there aren’t any new rivals, the ways to eliminate them are fun and exciting. Imagine when we finally get the tenth what it will be like if this is how it’s like with only the first rival! It’s amazing.

  8. I have found a bug, I think.

    I will give the steps how I think I found a bug

    1. Start a new game.
    2. do whatever for the intro scene and info’s Chan’s texting scene.
    3. Get 50 info points.
    4. get sedative.
    5. wait till Osana sets down her bento
    6. Giggle to distract the bullies..
    7. (this is part where it bugged for me) poison her bento.

    I did all of this steps to make osana go to the nurses room and I couldn’t poison her bento.
    I hope this doesn’t waste your time.

    • I see. I never added a “put sedative poison into bento” option to the bento that sits on top of Osana’s desk.

      Currently, the only method to put sedative in Osana’s bento is to do it at lunchtime by distracting her away from her bento once she sits down to eat.

  9. Yea yea, but he is adding the little things and fixes first. Isn’t fun to play a glitched game at all.

  10. Dude this feature is awesome this feature will be useful air you tubers like bijju mike that dude and a lot others nice job yandere dev keep on the good work. And one more thing please finish amai I’m so tired of waiting to her to be officially released.

  11. Ummm……. I tried to poison the gardening club members’ bentos in mission mode, but when I leave a weapon out, their bentos will appear on their hands. And some of the male students’ eyes have turned red (Except Sukubi because his eyes turned grey) whenever I dismember them. Please fix this thank you.

    • Same thing happened to me on Mission Mode, but my problem was that I tried to poison the other bentos, but they wouldn’t feel the effects of the poison. (They still continue to eat regardless). Or worse, I try to take the poison from Info-chan and it doesn’t let me take it the poison on the ground.

      • I think this will be fixed in the next build. If the bug is still happening in the next build, please e-mail me and let me know. (But describe the problem thoroughly.)

  12. hey im back again but ive noticed that musume has 6 dislikes rather than 5? she dislikes family even though she loves her dad since he buys her everything she wants, was this deliberate or was this a mistake?

    • Because in older builds Dev made most students who love or neutral to Violence to hate Violence
      That’s why some students have 6 dislikes now(the bullies and the delinquents now have 4 likes and 6 dislikes because of this)

  13. Because in older builds Dev made most students who love or neutral to Violence to hate Violence
    That’s why some students have 6 dislikes now(the bullies and the delinquents now have 4 likes and 6 dislikes because of this)

    • I’m sorry, no. For the time being, I’m going to continue fixing bugs and adding the remaining features that I want the game to have before I consider the demo “complete” and the only work remaining is to add the other rivals. That’s when the crowdfunding campaign will happen.

  14. Hi! i found a very annoying bug! everytime im pressing on the E prompt for a student but not to talk to them (pushing, drowning, pose mode menu…), its breaking. i dont know how to explain it, i guess you’d need to test it by yourself to understand what im saying.

    • I’m pretty sure that Ayano is 18 or 19, not 20. You can only drink alcohol in Japan if you’re 20 or older, Ayano is not. Which means she needs to get a fake id to quote unquote, “prove” she’s allowed to drink. All characthers are 18 or older, not 20 or older.
