August 19th Bug-Fixing Build

Darn – there were still a few nasty bugs lingering in the latest build of the game! I had to upload a new one. Scroll down beneath this chilling illustration by KarimeNami! I’m always surprised to see artwork that is so beautiful and so morbid at the same time!

  • Fixed bug that would cause Teacher’s Pets and Teachers to become stuck in place if the Teacher’s Pet tried to lead the teacher to a corpse after the player had destroyed that corpse.
  • Fixed bug that would cause students to perform their walking animation while moving at “run speed” if they witnessed a corpse or a murder while investigating a suspicious sound.
  • Attempted to fix bug that would cause Yandere-chan to permanently freeze if a teacher spotted Yandere-chan in a suspicious state while the teacher was running towards a corpse.
  • Fixed bug that would cause Social Butterflies to recognize Yandere-chan as a murderer even if she had been wearing a mask at the time she committed murder.
  • Fixed bug that would allow Yandere-chan to change her shoes at her shoe locker when wearing outfits that shouldn’t support shoe-changing.
  • Fixed bug that would cause teachers to not enter the “Struggle” animation if they were attacked while performing a reaction to a corpse.
  • Fixed bug that would cause Yandere-chan to permanently freeze in place if a teacher spotted her trespassing.
  • Fixed bug that would cause a mind-broken slave to continue talking and muttering to herself after death.
  • Fixed bug that would cause Social Butterflies to twitch when hiding in one of their hiding places.
  • Fixed bug that would cause a mind-broken slave’s “blood fountain” sound effect to not play.
  • Fixed bug that would cause a mind-broken slave’s weapon to be invisible.

August 18th Bug-Fixing Build

In this update, I think I’ve fixed almost all of the critical bugs that were plaguing the most recent build of the game. Scroll down below this super-awesome-looking Pokemon-themed illustration by Adoralla to read a list of everything that I fixed in this new build!

  • Fixed bug that was causing students to stare at the point in space where Yandere-chan was previously standing right before she attacked someone, instead of staring directly at Yandere-chan when she was attacking someone.
  • Fixed bug that would cause the player to drown Kokona by speaking to her at any point in the day, if the player had told Kokona to meet them at the school fountain earlier in the day.
  • Fixed bug that would allow Yandere-chan to walk around during the Game Over screen if Senpai spotted her committing murder using one of the new Sanity-Based attack animations.
  • Fixed bug that was causing Yandere-chan to hold her phone like she would hold a weapon if she was instructed to “Pass Time” while holding a weapon.
  • Fixed bug that was causing book-reading students to fail to return to their book-reading animation if they were interrupted while reading a book.
  • Attempted to fix bug that would cause Kokona to get called to the guidance counselor’s office even if she had been arrested by the police.
  • Attempted to fix bug that would cause Kokona to return Sakyu Basu’s stolen ring even if she was dead or arrested by the police.
  • Fixed bug that was causing weapons to not become bloody while Sanity-Based animations were enabled.
  • Fixed bug that was causing all kidnapped girls to appear in the basement as Musume Ronshaku.
  • Fixed bug that was causing Info-chan’s school uniform to be completely white.

By the way!

If you see an error message that says “Cannot Reach Download Source” when trying to download the newest build of the game, it means that I’m currently uploading a new build of the game! I’ll try to release a new version of the launcher that displays a more clear message sometime in the future.

Yikes! Yesterday’s build had a lot of bugs in it. I fixed as many critical bugs as possible, and uploaded a new build. Scroll down below this beautiful illustration by eisjon to see a list of all the bugs that I fixed.

  • Fixed bug that would allow Yandere-chan to pull off a stealth attack on a character who was clearly aware of her presence (running in fear after witnessing a murder).
  • Fixed bug that would cause the camera to focus on Senpai’s face instead of a teacher’s face, when a teacher caught Yandere-chan behaving badly.
  • Fixed bug that would cause Yandere-chan and Kokona-chan to be replaced by Musume Ronshaku during the Friendship Elimination cutscene.
  • Fixed bug that would cause all sorts of horrible problems if Yandere-chan attempted to perform a stealth attack on a teacher.
  • Fixed bug that would cause students to freeze in place if they were distracted by another student while reading a book.
  • Fixed bug that caused students to freeze in place if Yandere-chan tried to kill them while they were following her.
  • Fixed bug that would make it difficult to speak to Empty Husks / Placeholder Club Leaders from the front.
  • Fixed bug that was preventing infatuated female students from emitting hearts.
  • Fixed bug that would cause the syringe to trigger sanity-based animations.
  • Fixed bug that was causing all delinquents to have pure white clothing.

How Sanity Affects Murder in Yandere Simulator

The new build is finally ready! Here’s a YouTube video that will tell you all about it:

If you want to see a list of every little addition, fix, or tweak in this build, here’s a list:

Fixes And Changes:

  • The idea with Social Butterflies is that they would run and hide in heavily-populated areas. However, if a murder occurs IN a heavily-populated area, then Social Butterflies “hide” right where they are standing. To combat this problem, Social Butterflies now run to a collective hiding spot and huddle together, rather than “hide” in plain view of the killer.
  • Fixed bug that would cause the pink trail leading to class to fall through the ground. (This has caused the return of the bug that would cause the pink trail to exert physical force on other objects in the world. Finding a solution that prevents both bugs simultaneously is difficult.)
  • Researched and successfully implemented a method for modifying textures while the game is running. (You can currently only see one example of this in the game right now: Midori’s stockings and panties are now green.) This opens up tons of customization potential in the future!
  • Finally fixed that stupid bug that would cause teachers’ eyelids to deform in a bizarre manner during their blinking animation, and also fixed that stupid bug that would cause teachers’ irises to deform during their “eyes shrinking with fear” animation.
  • Previously, if a murder-suicide occurred above stairs, the difference in the heights of the two characters would the animation to become desynchronized. Now, a murder-suicide is no longer allowed to occur above stairs.
  • Fixed bug that would give the player a game over for holding a weapon – instead of a game over for murder – if the player committed murder in front of a teacher.
  • Fixed bug that would cause the murder-suicide animation to glitch out if Kokona was splashed with liquid or set on fire before the animation began.
  • Fixed bug that would prevent blood from spawning during a murder-suicide animation if the animation occurred above the ground floor of the school.
  • Fixed bug that would cause students to tilt at extreme angles if the player distracted them with a giggle while at a higher or lower elevation.
  • Students who have witnessed Yandere-chan commit murder will now always perform a face-hiding animation if she aims her camera at them.
  • Fixed bug that would cause Kokona to spin in place if she received a note in her locker telling her to meet a student at 7:00 AM.
  • Replaced Yandere-chan’s old placeholder home environment with a new one (trigger the “Befriending Kokona” cutscene to see it).
  • Fixed bug that would cause Kokona to do weird teleporting nonsense if she was splashed with water while changing her shoes.
  • Fixed bug that would cause Senpai be permanently frozen if he was startled by Yandere-chan while changing his shoes.
  • Attempted to fix bug that would cause students to get stuck on a wall when attempting to exit a bathroom.
  • Attempted to fix the bug that would cause corpses’ limbs to stretch out as they were being dragged.
  • Fixed bug that would allow the player to pause the game while being attacked by a delinquent.
  • Fixed bug that would prevent the player from using the “Go Away” command on Musume Ronshaku.
  • Fixed bug that would allow Yandere-chan to clip through walls after winning a struggle.
  • Fixed fire extinguisher signs that were pointing in the wrong direction.
  • Fixed janky camera movement after winning a struggle.
  • Smoothed camera movement after losing a struggle.
  • Added a new hairstyle to the game.
  • Fixed bugs in Bad Time Mode.
  • Added the ability to pray to a turtle.

Murder-Related Additions

  • Added new killing animations that play depending on the protagonist’s current level of sanity. You must speak to the turtle in the Light Music clubroom to activate these animations.
  • Added stealth attacks that only play if the protagonist attacks someone from behind. You must speak to the turtle in the Light Music clubroom to activate these animations.
  • If your Physical stat is above 0, it is now possible to have a struggle against a teacher, and kill that teacher.
  • Now, when a teacher is killed, they will be replaced the next day by a randomly-generated teacher.
  • Adjusted the blood spray particle effect of the murder-suicide animation.
  • Added new struggle animations (for students and teachers).
  • Added new sound effects to the murder-suicide animation.

What’s next?

I’m currently looking at three possibilities…

  • Implement Matchmaking
  • Create the Rival Introduction Video
  • Take care of a bunch of miscellaneous tasks (implement new inventory system, re-write some code so that it’s easier for me to make cosmetic changes to students, make changes to the school environment, etc.)

The way things might work is that I’ll start working on the Rival Introduction video, but I’ll run into some kind of roadblock (need new music, need adjustments to the artwork, need the voice actresses to re-record some lines) and then I’ll put the Rival Introduction video on hold and take care of miscellaneous tasks to pass the time while I’m waiting for the assets I need. Or, I’ll work on the Matchmaking elimination method while waiting for assets, instead.

Help me decide what my next top priority should be! Vote on this poll!

Update Coming Soon

Don’t shoot! The next update is almost ready. All I have to do now is fix one or two bugs, and then produce the update video. I don’t know if it will be ready within the next 3 hours, but it will definitely be ready within the next 27 hours. If the next build and video aren’t ready within the next 6 hours, then they will be ready sometime tomorrow afternoon or tomorrow night.

Here’s a preview:

See you soon!

Indestructible Rival 2

Hey, remember Indestructible Rival? I made a sequel!

“YandereDev, you baka! Why are you spending your time making videos like this instead of working on the game?!”

Well, I produced this video in my spare time, and only worked on it if I felt like I had recently made very significant progress on the game. I don’t feel guilty about doing something fun and silly in my spare time…

…but, you know what I do feel guilty about? Easter eggs. I’ll explain.

I think that there are two different Yandere Simulators. There’s the one that exists in reality, and then the one that exists in my mind.

In my mind, Yandere Simulator is a horror game where you play as the monster. The protagonist specializes in sabotaging other peoples’ lives using every tool available to her, whether it’s gossiping, bullying, kidnapping, or worse. There is no boundary that the protagonist won’t cross; psychological torture, animal cruelty, and outright murder are all viable options, as long as they get her closer to what she wants.

In my mind, Yandere Simulator is a stealth game, but not a traditional stealth game; it’s a social stealth game. It’s not about hiding around corners…it’s about hiding in plain sight. You must hide your true nature so that nobody learns you are a bloodthirsty psychopath. You must hide your intentions so that nobody will suspect that you’re about to spill their blood. You must hide the truth from people so that you can deceive and manipulate them.

However, the Yandere Simulator that exists in reality is something quite different.

Working on such a grim, dark, and morbid game can get very tiresome, so sometimes I briefly pause development and  create silly things just for fun. If I didn’t take short breaks to relax and create humorous things, I’d probably go insane from spending hundreds of hours working on such a morbid game! My humorous “easter eggs” have resulted in many smiles and laughs…but they have also had an unintended side-effect.

A “game” is something that has win conditions and loss conditions. It is currently impossible to “win” Yandere Simulator; in other words, it doesn’t even qualify as a game right now! Because Yandere Simulator is so far from completion, the easter eggs are some of the only ways to enjoy Yandere Sim. Unfortunately, the silly content has received far more attention than I ever anticipated, and has become a part of the game’s identity.

As a result, Yandere Simulator is often perceived as a joke game or “meme game”, which is the exact opposite of what I want. I have only myself to blame for this, since I’m the one who put in so many goofy easter eggs.

The solution may be to completely re-brand Yandere Simulator. To create the “horror game vibe” that I’ve always wanted it to have, many aspects of the game may need to change; the color scheme, the user interface, the soundtrack, and everything else that gives a game its “look and feel”. I’m going to focus on gameplay for the remainder of 2016…but, in 2017, the game’s branding may change completely.

This point in time – while Yandere Simulator is still regarded as a “joke game / meme game” – is the only point in time when it will be appropriate for me to produce “silly” content. After the Great Rebranding, I’ll have to abstain from silly “just for fun” stuff. So, before that time comes, I wanted to have a little fun, and produce a video that celebrates Yandere Simulator’s goofy side…and that’s where “Indestructible Rival 2” came from.

In short, this may be the last – or one of the last – “silly” videos that I produce, as part of my effort to stop producing content that would result in a “meme game” stigma.

With all of that said, I fully acknowledge the possibility that I could alienate a huge chunk of the game’s fanbase by rebranding the game. A lot of people probably became fans of the game because of the current balance of whimsical content and dark content, and wouldn’t find the game appealing if it moved too far in a different direction. This is something that I’m very concerned about, so this is a decision that I won’t be making without feedback.

Well, if you’ve been following this game’s development for a while, then you probably know what I like to do in situations like this…yes, that’s right:

It’s poll time!

August 2nd Bug-Fixing Build

(Edited at 4:00 PM PST. Scroll down to read the edit.)

Help! I can’t stop releasing bug-fixing builds! It keeps happening!

Scroll down past this absolutely gorgeous illustration by the amazing Yu Yumihana to see a list of everything that is fixed in the latest build of the game!

  • Fixed bug that would cause the game to freeze if the player disposed of the corpse of a character involved in a murder-suicide before the police arrived.
  • Fixed bug that would cause Teachers Pets to tilt at bizarre angles after reporting a murder to their teachers and then hiding in their classrooms.
  • Fixed bug that would cause Oka to perform her “spying on the Basu sisters” action even if the Basu sisters were dead AND her club was closed.
  • Attempted to fix bug that would cause the police to obtain information from witnesses who were killed after seeing whatever they had witnessed.
  • Fixed bug that would cause students to tilt at bizarre angles when Yandere-chan spoke to them while standing at a higher or lower elevation.
  • Fixed bug that would cause weapons to be visible penetrating through a mind-broken slave’s body as they walked toward their victim.
  • The player can now leave a note in Kokona’s locker even if they have not eavesdropped on her Monday conversation.
  • A character who has changed out of her school uniform will now no longer try to change shoes at their locker.
  • Fixed bug that would cause Mai Waifu’s left eye to not cycle between colors when she was kidnapped.
  • Fixed bug that would cause some voiced lines to not play audio.
  • Implemented better “check locker for note” animations.
  • Improved the mind-broken slave’s suicide animation.


Oops! Found a couple of serious bugs – had to release another bug-fixing build!

  • Fixed bug that would prevent the player from being able to leave a “Domestic Abuse” note in Kokona’s locker the same day they eavesdropped on her rooftop conversation.
  • Fixed bug that would cause Kokona to leave school before 5:30 PM even if she had accepted a note agreeing to meet someone on the rooftop at 5:30 PM.

Hey! Where’s the update?!

I always try to release a “major” update at least twice a month – on the first and fifteenth days of every month. For example, August 1st and August 15th. So…where’s the update?

The last “major” update was a mere week ago, on July 24th. I’m still going to aim for two major updates per month, but it looks like I’ve been thrown off of my “1st and 15th” schedule…so, when should you expect the next build?

I’d love to say that the next update will be ready by August 7th, but it’s possible that I might need more time than that. I really don’t want that to be the case, so I’m going to work extra hard to get this update out to you as soon as possible! I hope that you’re going to enjoy it once it’s ready!

Edit – August 1st 4:00 AM

Oh, boy! I learned a few things tonight!

My plan was to make the next update combat focused; I was planning to add the ability to fight against teachers, and add “sanity-based killing animations” – in order words, the lower your sanity, the more prolonged and brutal your killing animations would be.

I believed that I had all of the assets required to implement the new sanity-based combat system, but now that I’ve had a chance to review all of the animations that were delivered to me, I’ve come to realize that a few adjustments are required.

I feel 100% satisfied with the “short, bladed weapon” animations and circular saw animations, but I feel that the “long, blunt weapon” animations need some improvement. I’ve also learned that some of the “long, bladed weapon” animations use incorrect timing and will require adjustments. As a result, I can’t implement the sanity-based combat animations at this point in time. I can write the code and set up the system, but without a complete set of all required animations, the system can’t go live.

So, when will I have improved “long, blunt weapon” animations and fixed katana animations? It’s difficult to say; the animation volunteers have lives of their own. They have jobs, school, family, et cetera. I’ll just have to wait patiently until they become available to help me out.

On the plus side, I don’t think there is anything stopping me from adding the ability to fight back against teachers. I can also use this time to work on the rival introduction video. I can also use this time to implement Matchmaking.

In short, the new sanity-based combat system won’t be implemented as soon as I hoped it would, since I need to wait for animation adjustments. However, I’m still going to write the code for the new system, so that it can be activated as soon as I get the new assets. Additionally, the development of other new features will continue at full speed.

Thank you for your patience, and thank you for following the development of Yandere Simulator!
