September 20th Bug-Fixing Build

A new build is available! Click here to grab it!

You know the drill! Scroll down past the pretty fan-art by alicerbear to see a list of the latest bug-fixes.

  • Fixed bug that would cause puddles of water to count as puddles of blood, and require cleaning in order to fulfill the “mop up blood” objective for escaping arrest.
  • Fixed bug that would cause the purple-haired girl to freeze in place when checking her locker for a note, unless the player was pointing the camera at her.
  • Fixed bug that would prevent Yandere-chan from interacting with other students after using a garbage bag to cover a corpse up with trash in the dumpster.
  • Fixed bug that would cause Yandere-chan to freeze in place permanently if the player pressed the crouch button while simultaneously attacking an NPC.
  • Fixed bug that would allow the player to dump water on the purple-haired girl’s head multiple times in a row, causing many buggy side-effects.
  • Now, when Senpai witnesses Yandere-chan commit murder, all students freeze in place and look at Yandere-chan with horror.
  • Fixed bug that would cause Yandere-chan to laugh endlessly without ever stopping if she was laughing as the day ended.
  • Fixed bug that would cut off a character’s speech if Yandere-chan took a photograph while a character was speaking.
  • Fixed bug that would make the new student (Ryuto) appear bald after the witnessed murder.
  • Added cloth physics to Ryuto’s bandana, thanks to help from Saracen!

Unless some super serious bugs are discovered between now and October 1st, this is probably the last “bug fixing” update for now. I hope I took care of all the more noticeable problems!

September 19th Bug-Fixing and Framerate-Improving Build

There were some embarrassing bugs in the previous build (as usual) so I’ve prepared a new build with some fixes. I also found several ways to increase the framerate dramatically! I’m noticing a big improvement in the framerate, myself. Let me know if you get better performance out of this build!

As usual, scroll down past the awesome fan-art to read about what’s new in this build.

If that fan art isn’t your style, then maybe check out this short comic by SRealms!

  • Fixed bug that would screw up the subtitles of a cassette tape if the player pressed a directional button while simultaneously pressing “Play” on the tape recorder.
  • Modified cloth physics / hair physics code so that physics are not active if that character is far away from the camera. This should improve the framerate.
  • Modified the character animation code so that characters are not animating while they are not being rendered. This should improve the framerate.
  • Fixed bug that would cause a weapon’s button prompt to appear to its side rather than above it, after the weapon was dropped.
  • Fixed bug that would cause a girl’s textures to freak out if she was pushed off the school rooftop while in her gym uniform.
  • Fixed bug that would cause the game to disable the “Pass Time” feature on Yandere-chan’s phone at the wrong times.
  • Fixed bug that would prevent the “Swap _____ for _____” text to appear above the knife on the school rooftop.
  • Made some corrections/additions to the Student Info pages.
  • Fixed bug that was causing errors during Titan Mode.
  • Added orange and brown hair colors for Senpai.

Don’t worry, I’m aware that there are still more bugs that need to be fixed in the game. There may be more bug-fix updates in the next few days. (I just hope that the tricks I’m using to improve the framerate don’t result in any new bugs!)

I believe that the next “big” update should arrive on October 1st. (…Unless I spend the majority of the next 11 days fixing bugs, that is…)

Bug Fixes and Student Info

It’s been 17 days since the last update, so I decided to upload a new build containing my most recent progress and a bunch of bug fixes.

To read about everything that is new in this update, scroll down past this beautiful artwork by alicerbear!

First, let’s get the miscellaneous additions and bug fixes out of the way:

  • The outfit that the player has chosen for Yandere-chan will now be displayed on the title screen. (For debugging purposes, Yandere-chan’s title screen outfit can be changed using the F1, F2, F3, F4, and F5 keys.)
  • Fixed bug that would allow Yandere-chan to freely run around in the “Heartbroken” game over screen if Senpai spotted her committing murder under very specific circumstances.
  • Added a button prompt inside of Yandere-chan’s room that explains what button you’re supposed to press in order to access things (panties, corkboard, door, etc).
  • Added an option in the Easter Egg menu to disable copyrighted music while Easter Eggs are active, so that YouTubers don’t get their videos flagged.
  • Fixed bug that would cause Yandere-chan to perform the mopping animation without a mop in her hands if the player crouched while she was mopping.
  • Fixed bug that would cause the “Lowest School Atmosphere” music to play when the “Highest School Atmosphere” music should have been playing.
  • The player can now use the D-Pad to navigate the Challenge screen in addition to the keyboard and thumbsticks.
  • Fixed bug that would cause an electrocuted girl to stop being electrocuted if she heard Yandere-chan laughing.
  • Fixed bug that would make it possible to view Challenge images while leaving the Challenge screen.
  • Modified “DK Mode” so that now all students are affected by it, not just Yandere-chan.
  • The school uniform that you choose for Yandere-chan now appears inside of her home.
  • Fixed bugs with keyboard navigation at the Challenge screen.
  • Fixed Midori Gurin’s hair in her Student Info portrait.
  • Fixed Pippi Osu’s hair in her Student Info portrait.
  • Changed the “horror” music at the title screen.
  • Added music to the “DK Mode” easter egg.
  • Added a new student to the game.

Student Info

The game’s newest feature is something that may not seem very exciting at first glance, but will actually be very important in the final version of the game. It’s the Student Info screen!

The Student Info screen will tell you which students you have taken a picture of, which students are dead, and which students you have taken a panty shot of.

Taking a picture of a student will show you their Student Info, which can be accessed at any time from the Student Info menu.

Info-chan now displays more information than she previously did: This screen now displays a student’s reputation and also some additional information about them.

Some students need to be stalked before their “Additional Information” section is filled out:

You might think that this new feature is boring, because it’s not directly related to harming your victims. However, this screen will actually be an essential part of the next elimination method that will be added to the game! Just you wait; very soon, you will learn just how important the Student Info screen can be!

If you have a keen eye, you may have noticed that there seems to be a new student in-between Pippi and Midori on the Student Info screen…just who could that be, I wonder?

Quiet Contest Results

Wow! The Quiet Contest got way more attention than I anticipated! There were 113 entries for the contest. That just blows my mind!

Some submissions were joke entries that were sent in for a laugh, but a lot of people actually took it quite seriously!

The final decision came down to a set of 21 super high-quality submissions. It was extremely difficult to decide on the winner of the contest, since it’s very hard to pick the “best” illustration when every one of them is so great. I’m very afraid of people saying, “Ugh, why did THAT artist win? Another artist should have won!” but I suppose that’s just the risk I take when holding a contest.

It was nearly impossible for me to pick the winner; I deliberated about it for over an hour, constantly flipping back and forth between illustrations, saying “This is the winner. NO! This is the winner. No, wait! This one…” In the end, I chose the illustration that seemed to carry the spirit of Metal Gear Solid most closely.

So, without further ado, I present the winner of the contest, the immensely talented PixelNoodle!

What an absolutely gorgeous illustration! I can feel the inspiration of Yoji Shinjawa’s brushwork. You feel it too, don’t you?

As I promised in my previous blog post, I’ll share with you the most remarkable “runners-up”, the people whose entries stood far above the rest:

Top 20 Runners Up

Honorable Mentions

I’d also like to call attention to these gorgeous illustrations by the incredibly talented 殇子 Black Chan:

Kokona certainly looks rather fetching in a swimsuit, doesn’t she?

Final Words

In case you’d like to see every single illustration that was submitted for the contest, here’s a link to a file containing every single submission:

I’m honored that so many people were interested in entering the contest! I feel really guilty about picking one illustration and labeling it as the “winner”, since there were many other illustrations that I absolutely loved. I hope that all of the participants enjoyed the time that they spent creating their artwork, I hope that all of you enjoy seeing the beautiful images that were created for this competition!

My two-week vacation from Yandere Simulator was quite productive, but it ends tomorrow. I’m very eager to get back to work on the game!

By the way, how often do you think I should hold art contests?

Yandere Simulator Fan Art Contest

I’m on vacation until September 15th, but I still want to update the blog with as many interesting things as I can. I’d like to try something new, and see if anyone enjoys it.

What I’d like to try first is…a Fan Art Contest!

A new Metal Gear Solid game just came out, so I think it would be appropriate to ask people to draw Yandere-chan cosplaying as Quiet from Metal Gear Solid V: The Phantom Pain!

The winner of the contest will receive a Steam code for Metal Gear Solid V: Ground Zeroes and a code for Metal Gear Solid V: The Phantom Pain! I’ll also be happy to link to your DeviantArt/Tumblr/whatever you’ve got, so that everyone can check out more of your artwork.

The deadline for the art contest is September 13th. On September 14th, I’ll make a blog post naming the winner of the contest, and show off the illustrations that almost won the contest.

The contest rules are:

  1. You’re allowed to include multiple characters in the illustration. For example: Yandere-chan perched on the school rooftop, aiming a sniper rifle at Osana Najimi as she talks to Senpai-kun.
  2. You’re allowed to modify Quiet’s clothing so that Yandere-chan is wearing a cross between her normal school uniform and Quiet’s clothing, or just draw Quiet’s clothing with 100% accuracy.
  3. You’re allowed to submit more than one illustration, although this does not increase your chances of winning.
  4. September 13th is the final day that you’re allowed to submit your illustration. I will not accept any submissions past September 13th.
  5. You must include the words “Quiet Contest” in your e-mail’s subject line, or else it may be impossible for me to find your entry among all of the e-mails that I receive every day.

If you need to know any other specifics, please ask in the comment section below.

In case you’ve been living under a rock for the past 2 years and don’t know what Quiet looks like, here are some reference images:


Isn’t she just magical?

If you would like to see reference images of Yandere-chan, you can find one here and one here.

If people seem to enjoy the idea of a fan art contest, then there might be one contest per month, with a different reward each time!

So, what do you think? Is this a good idea? A bad idea? Do you have any ideas for fun fan-engagement activities? Please let me know in the comment section below!

Yandere Simulator Infographic

If you’re looking for information about the latest build of the game, click here!

The folks over at have taken the time to compile an infographic about Yandere Simulator! They clearly spent a lot of time working on it, and most of this data is very interesting to me, so I’ve decided to share their infographic with you all!

Be sure to visit this blog tomorrow to hear about the contest that I’ve been planning!

School Atmosphere Update

EDIT: Bugs were found and fixed. A new build is now available.

School Atmosphere has finally been added to the game! This new feature affects almost everything about the game. Here’s a video that explains all of its current effects:

Here’s a full list of everything that’s new in this build:


  • Added a “Choose Uniform” interface to the “Customize Senpai” screen. The player can now choose what uniform the school’s students will wear.
  • There are now 5 uniforms available for male students.
  • There are now 5 uniforms available for female students.
  • It is possible to apply custom textures to all 5 of Yandere-chan’s possible school uniforms.
  • The process for applying custom textures to Yandere-chan has changed slightly. There will no longer be a “CustomArms.png” and Yandere-chan’s arm texture will now come from “CustomUniform.png”. I apologize for any custom textures that break because of this!
  • It was only possible to add new uniforms to the game because of a tremendous amount of assistance from Saracen!

School Atmosphere

  • If a student stops coming to school (because they were killed or kidnapped), School Atmosphere will drop slightly.
  • If a corpse is discovered, School Atmosphere will drop significantly.
  • As School Atmosphere drops, the school becomes darker and less colorful.
  • As School Atmosphere drops, the game’s background music changes to suit the mood of the school. These new music tracks were composed by Henry Rofkar of Only Wednesday Music!
  • As School Atmosphere drops, students will become more paranoid.
  • A paranoid student can notice dangerous behavior from a farther distance.
  • A paranoid student becomes alarmed faster than a normal student.
  • A paranoid student’s idle animation is similar to the movement of a security camera (looking left and right) increasing the chance that Yandere-chan will be spotted by them.
  • As School Atmosphere Drops, Yandere-chan will lose more reputation points from dangerous behavior (carrying weapons, looking bloody, acting psychotic).
  • Now, when a student is murdered, they will scream. If a student hears a scream, they will react by turning in the direction of the scream.
  • As School Atmosphere drops, students will react to screams from longer distances.
  • The “mood” of the Calendar Screen changes to reflect the current level of School Atmosphere, and displays a number and a graphic that relates to the current School Atmosphere level.

Miscellaneous Additions

  • If Yandere-chan steps into a puddle of blood while barefoot, she leaves behind a bloody footprint instead of a bloody shoeprint.
  • Students will now react to Yandere-chan when she is laughing in a sadistic and psychotic way. This will cause reputation loss.
  • Added more options to the Debug Menu (accessed by pressing the “\” key on your keyboard).
  • Added a “stab” sound effect when stabbing students.
  • Added a new sponsor to the sponsor screens.

Bug Fixes

  • Fixed bug that would allow Yandere-chan to clip into the bathtub in the shower room by running towards the purple haired girl while she was bathing (I think).
  • Fixed bug that would cause objects to grow larger and larger in size every time they were picked up and dropped by Slender-chan or DK-chan.
  • Fixed bug that would cause Yandere-chan’s textures to get screwed up if Easter Eggs were activated while she was nude.
  • Fixed bug that was preventing outlines from appearing on male students’ heads in Yandere Vision.

I’m going to take a two-week vacation from game development now, but I have some noteworthy blog posts planned for the near future, including a contest that I’m very excited about! Please keep checking in for updates!
