Fall Girl, a Yandere Sim Fan Comic

If you’d like to enjoy something yandere-themed while waiting for the next update to arrive, I’ve got just the thing for you!

An extremely cool person has just finished illustrating a Yandere Simulator fan comic! I think it’s really awesome, and I think you should check it out!


July 22nd Bug-Fixing Update

July 23rd 2:35 AM Update: New Download Link

It took quite a while, but I finally found a window of time to produce a new build for the game with some bug fixes and a handful of new additions! Nothing huge, though. The next “big” update, containing new features, will most likely occur on August 1st…unless some kind of catastrophe gets in the way, like receiving another avalanche of annoying e-mails.

As usual, visit the Downloads page to grab the latest build! For a list of all the changes in this build, scroll down past this gorgeous fan-made illustration:

What’s new in this build?

  • Fixed bug that would cause Yandere-chan’s fingers to deform in strange ways when she raised her phone camera (thanks to help from Saracen again).
  • Fixed a bug that would prevent Yandere-chan from picking up items that were dropped near the small gate nearby the school entrance.
  • Fixed bug that would cause the “Caution” symbol to appear onscreen even when Yandere-chan was holding a non-suspicious object.
  • Made the options at the Game Over screen grow and shrink when selected / deselected.
  • Fixed another bug that could result in the “only Senpai comes to school” scenario.
  • Attempted to fix the “teachers get stuck on doorways” bug.
  • Added several new accessories for Yandere-chan.
  • Added several new sponsors to the game.

E-mails, Volunteers, and Progress

It’s time to give you an update on Yandere Simulator’s progress!  This time, I had so much to say that I went over YouTube’s 15-minute limit, and had to make two videos!

These videos are quite unlike my previous videos in nature. These videos primarily focus on some problems that have been slowing down development of the game recently, and also address some comments that I hear dozens of times per day.

I hope that those two videos weren’t a downer! I had to spend a lot of time elaborating on negative subjects in order to thoroughly explain why I don’t have anything new to show off this week. Hopefully, those videos weren’t too whiny or depressing.

Now that I’m finally past the mountain of e-mails that prevented me from getting any work done over the past two weeks, I should be able to make some real progress on the game and have something impressive for you by August 1st!

…but that’s only if I don’t get swamped with e-mails again! So make sure to read this post and this page in order to avoid wasting my time!

Remember: Every time you ask me a question that I’ve already answered hundreds of times, a yandere girl loses her Senpai!

Volunteer Update

Oh, dear. That didn’t work at all!

In an attempt to re-connect with old volunteers whose contact information I had lost, and make it easier for me to organize my e-mails, I made a Volunteer page with clear instructions on how to contact me if you’re a volunteer. The result was a flood of new e-mails from people offering to volunteer to help out with the game. Since then, I’ve spent around 8 ~ 12 hours a day reviewing and replying to volunteers.

Even though I’ve been doing literally nothing but eating, sleeping, and reading e-mails for the past several days, I’ve still got dozens of e-mails remaining to answer, and I seem to be getting new ones at a faster rate than I can answer the old ones, so the pile only keeps growing! Most of the e-mails that I’m replying to are several days old already.

On one hand, it’s extremely heartwarming to know that so many people are generously offering to help out with Yandere Simulator. On the other hand, not a single new line of code has been added to the game since July 1st, aside from bug fixes.

Most volunteers who contact me are very skilled people, but I find myself not able to give them any tasks, because all tasks have already been taken up by the first people who volunteered. I constantly find myself thinking, “Drat, I shouldn’t have given the task to THAT guy. This other volunteer is WAY more skilled. I should have given the task to HIM, instead!” It’s an absolutely terrible situation to be in.

Because I’m going to be doing absolutely nothing but answering e-mails for the foreseeable future, it looks like it’ll be absolutely impossible to include anything remarkable or noteworthy in the game by July 15th. This is extremely disappointing to me, since the new Volunteer page was supposed to help development, not bring it to a complete halt. I don’t use the phrase “absolute disaster” very often, but I don’t know how else to describe this situation.

If you’re one of the people who e-mailed me at any point in the past week, I deeply apologize for how long you’ve had to wait for a response.

On a more positive note, the past week has put me in touch with dozens of extremely talented people who I’m absolutely honored to be acquainted with, and once I’ve “separated the wheat from the chaff”, so to speak, Yandere Simulator is going to have an absolutely awesome team behind it.

How can I help?

This is going to sound very harsh, but in the interest of saving my time and your time…

  • Don’t volunteer to be an artist if you can only draw stick figures.
  • Don’t volunteer to be a voice actor if your microphone sounds like a tin can and a string.
  • Don’t volunteer to be a 3D modeller if your idea of “texturing” is downloading an image from Google and putting it onto a model with no UV mapping whatsoever.

July 4th, 5th, and 7th Bug-Fixing Build

Last Updated: July 7th, 12:00 AM

Although the 4th of July is an American holiday, Japan also celebrates several summertime holidays and festivals with fireworks displays.

Wouldn’t it be fun to wear a yukata, follow Senpai to a festival, and use the sound of exploding fireworks to mask the screams of a girl you’re murdering?

In any case, I’ve uploaded a new build with some bug fixes!

July 4th:

  • Fixed bug that would cause the camera to teleport to Senpai if a teacher spotted Yandere-chan in an incriminating state while guarding a corpse.
  • Fixed bug that would cause the purple-haired girl to slide across the ground after witnessing murder if she witnessed murder during an event.
  • Fixed bug that would cause the purple-haired girl’s animations to break if speeding up the game before she arrived at school on a Monday.
  • Fixed bug that would cause the game to freeze if Senpai and a teacher both observed Yandere-chan near a corpse simultaneously.
  • Attempted to fix bug that would cause characters’ eyes to point in opposite directions after witnessing murder.
  • Fixed bug that would cause Pippi’s pathfinding to break after 4:00 PM.
  • Changed Yandere-chan’s pantyhose into stockings.

Yes, that’s right, Yandere-chan no longer wears pantyhose. From now on, she will be wearing black stockings. The reason is because pantyhose would interfere with the various panties that the player can tell Yandere-chan to wear. So, she’s got to wear stockings from now on.

July 5th:

  • Fixed bug that would cause the purple-haired girl’s Wednesday lunchtime event to glitch out if the player spoke to her and asked her to follow Yandere-chan before going to the rooftop, or if she witnessed Yandere-chan doing something suspicious in the middle of her event.
  • Fixed bug that would cause the police timer to disappear if the purple-haired girl died of poison while it was displaying onscreen.
  • Fixed bug that would cause the purple-haired girl’s lunchtime event to take place even if Senpai was not present.
  • Fixed bug that would cause the game to crash if Yandere-chan annoyed Senpai while trespassing in his classroom.
  • Fixed bug that would cause the game to become unresponsive if a teacher caught Yandere-chan misbehaving.
  • Attempted a fix for the “Students don’t arrive at school, even if they were alive the previous day” bug.
  • Added a Debug Menu accessed by pressing the “\” key. (This is the back-slash key, not the forward-slash key. It should be located beneath the Backspace key and above the Enter key.)
  • Yes, that’s right, Yandere-chan no longer wears pantyhose. From now on, she will be wearing black stockings. The reason is because pantyhose would interfere with the various panties that the player can tell Yandere-chan to wear. So, she’s got to wear stockings from now on.

July 7th:

  • Fixed bug that would cause button prompts to stop appearing over the purple-haired-girl and cyan-haired-girl, preventing interaction with them after their Monday lunchtime conversation event.
  • Fixed bug that would cause Yandere-chan to tilt her body at extreme angles if she was noticed by Senpai while Senpai was at a different elevation than her.
  • Fixed bug that would cause the purple-haired-girl to walk at super speeds if she was following Yandere-chan before an event occured.
  • Fixed bug that would cause the lighting to dim at certain locations on the rooftop.
  • Adjusted how much the – and + buttons change the speed of time.

Other News

  • Replying to the avalanche of e-mails that I get every day was always a challenge, but now I believe I’m actually receiving e-mails at a faster rate than I can answer them. If you’ve e-mailed me anytime in the past 72 hours, I have absolutely no idea when you should expect a response, because it’s going to take me a really long time to get through all of this mail.
  • I’ve gotten tons of bug reports, but I haven’t had a chance to read all of them yet, because I simply get way too many e-mails. Hopefully, sometime soon I can upload another build that fixes all of the other bugs that have been reported recently.
  • I hate to say it, but it’s looking extremely likely that I might not be able to implement very much new content into the game on July 15th, because I now spend 90% of my time writing e-mails and 10% of my time writing code for the game.
  • If you’re not reporting a bug, volunteering to help with the game, making a business proposal, or sharing fan art, please don’t e-mail me.
  • If you’re a volunteer, make sure to visit the new Volunteer page!


Many people have advised me to get a secretary to filter my e-mails and answer dumb questions for me. I dislike the idea, because:

  1. I don’t want to babysit a secretary until they’re doing their job properly.
  2. I don’t want to risk the secretary responding to questions incorrectly and spreading misinformation.
  3. I don’t want to risk the secretary filtering my e-mails incorrectly and failing to send me important e-mails.
  4. I don’t want to risk the secretary being lazy and going through e-mails so slowly that I’m better off doing it myself.
  5. I don’t want to risk the secretary seeing spoilers or other confidential information and then talking about it on social media.

In other words, I only trust myself to handle the task of checking my e-mail and responding to questions / corresponding with volunteers. I don’t want to risk someone else screwing things up.

The New “Volunteer” Page

If you’re looking for information about the most recent build, please click here.

I’d like to announce a new page for this blog: the Volunteer page!

The purpose of the new page is to establish a format for e-mailing me. If you don’t e-mail me using the format described on that page, it will be impossible for me to locate one of your e-mails or contact you when I need to. I get a lot of e-mails, and if the subject of your e-mail is generic, I’ll never be able to locate it or remember who you are and contact you in the future.

I’ve also created a Google Doc spreadsheet that lists all of my current needs for the game.

Message To All Volunteers

If you have ever volunteered to help out with Yandere Simulator, this message is for you!

Previously, I thought that I would never have the problem of having so many e-mails that I wouldn’t be able to find a specific e-mail or contact a specific person. So, I never compiled a formal document listing every volunteer and how to contact them.

In other words, if you’ve ever contacted me and said, “I’d like to volunteer,” and I said “Cool, I’ll contact you one day!” well, I don’t actually have any way to find you or contact you anymore, because your e-mail has been buried in the never-ending avalanche of e-mails that I get on a daily basis.

From now on, every time someone volunteers to help out with the game, I’ll add their contact information to a document so that I can contact them in the future. If you volunteered to help out with Yandere Simulator before July 2nd 2015, and you want to keep helping out in the future, then you need to contact me again so that I can include you in my volunteer document!

So, if you’re willing and available to help out with Yandere Simulator, please e-mail me using the format described at the bottom of this page and include examples of your previous work so that I can write your name and specialties in a document.


A Build, a Video, and a Poll

Last Updated July 1st 2:35 AM with bug fixes

If you’re looking for the most recent build, click here.

I’ve been trying to add a new elimination method to the game once every two weeks. May 15th was rooftop-pushing, June 1st was poisoning, June 16th was drowning…I really wanted to include another elimination method in the game for July 1st, but I wasn’t able to pull it off with the amount of time I had available. I could have implemented a bare-bones version, but it wouldn’t have been very exciting or interesting. So, I’m postponing the next elimination method until July 15th.

So, what do I have for you today, on July 1st? I have a new build and a new video. The latest build doesn’t have a new elimination method, but it does have lots of bug fixes, as well as several additions / improvements that you can read about below.

Today’s video is a bit different; instead of making a video about the latest new additions to the game, I made a video where I examine a game that is similar to Yandere Simulator, and discuss which features might be beneficial for Yandere Sim. At the end of the video, I pose a question that I’d love to hear your answer to.

Now that you’ve seen the video, how about answering a poll for me?

You’ll have to paste the link in your address bar: poll.fm/5c0lb

If you’re interested in seeing a list of all of the changes in the latest build, have a look:

Bug Fixes

  • Fixed bug that would allow Yandere-chan to apologize for interrupting a conversation (there is no reputation loss for doing so, so there is no need to apologize).
  • Fixed bug that would result in the “Drown” prompt not disappearing if the purple-haired NPC witnessed a murder during her “Stand Near Fountain” event.
  • Fixed bug that would allow the player to speak to an NPC when that NPC was supposed to be heading to a meeting place.
  • Fixed bug that would cause an NPC to slide across the ground if they witnessed a corpse while following Yandere-chan.
  • Fixed bug that would cause a poisoned girl to stop choking to death if she noticed Yandere-chan taking a panty shot.
  • Fixed bug that would cause Yandere-chan to be unable to pick up an item if she was standing directly on top of it.
  • Fixed bug that would prevent events from being interrupted even when Yandere-chan was bloody / armed / insane.
  • Fixed bug that would cause some students to continue walking around when Yandere-chan was spotted by Senpai.
  • Fixed bug that would cause girls’ hair to show up incorrectly when viewing their Info-chan profile.
  • Fixed bug that would make the “Pippi” character stand in front of her locker instead of playing video games.
  • Fixed bug that would cause students to sprout ponytails when Yandere-chan was spotted by Senpai.
  • Fixed bug that would make an NPC immune to weapons if she was in the middle of an event.
  • Fixed bug that would cause events to trigger when Yandere-chan was spotted by Senpai.
  • Fixed bug that would cause NPCs to ignore corpses lying in doorways.
  • Attempted to fix a bug that would cause an Event to occur even if one of the NPCs involved in that event was dead.


  • All buckets are now empty until Yandere-chan fills them up at a water source.
  • Buckets of water now get bloody when Yandere-chan dips a bloody mop inside.
  • It is now possible to dump a bucket of bloody water into a large sink.


  • Changed the appearance of the timer that appears when the incinerator is activated.
  • Changed the appearance of the incinerator model.
  • Added flames when activating the incinerator.
  • Added sound effects to the incinerator.


  • Added new accessories. One of the new accessories has a bonus feature attached to it! Can you find it?
  • Updated the teacher’s voiced lines.
  • Reverted title screen music.

2:35 AM Update

  • Fixed bug that would cause the game to freeze after getting caught by a teacher.
  • Fixed bug that would prevent the player from drowning the purple-haired girl.
  • Fixed bug that would prevent the gym doors from opening.
  • Removed the “blast off” feature, because I never programmed in a method for returning to Earth after leaving the planet.

This is still a huge problem for me, and I encourage you to read it if you are considering contacting me about anything at all.

Blog Post Tomorrow!

Tomorrow, I will be making a blog post aimed at past, present, and future volunteers. If you’ve contributed to Yandere Simulator in the past, or if you’re considering contributing in the future, you’ll definitely want to read tomorrow’s blog post!
