New Build Coming Soon!

I always try to upload a new build of the game on the 1st and 15th days of every month, right when the clock strikes midnight (in the PST timezone, that is). I won’t be able to upload a new build within the next 3 hours, but I feel very confident that it will be ready within the next 27 hours!

In the meantime, you can check out this absolutely stunning illustration by sm-exery!

Yandere Simulator Is Banned From Twitch

Yesterday, Yandere Simulator was banned from That’s a real shame, because is, by far, the most dominant game streaming website on the Internet. Twitch almost has a monopoly on game streaming. There are some noteworthy competitors, but Twitch’s reach and visibility is beyond anything else available. As a result, when Twitch refuses to allow a certain game to be broadcasted, it deprives that game of a lot of visibility.

You can find out more information by watching this video:

In this video, I mentioned that I’d be willing to modify some of the game’s content in order to make it acceptable for broadcast – the key word there is “some“. I would only be willing to change minor and insignificant things that aren’t part of my vision for the game, such as the skin texture during Titan Mode or the size of steam clouds on a nude character’s body. I would not be willing to remove gameplay mechanics or change parts of the game that are essential to my vision, such as torture, bullying, panty shots, erotic manga, the ability to kill students in a school setting, etc.

I hope that Twitch re-examines their criteria for banning a game from their service. I hope that Twitch realizes that Yandere Simulator isn’t anywhere near as bad as many of the other games that they’ve banned. I hope that Twitch realizes that they presently allow people to stream games that are far worse than Yandere Simulator. I hope that Twitch revokes their ban on Yandere Simulator.

However, I’m not going to hold my breath.

January 15th Progress Report

I’m not sure whether to call this a “Progress Report” or a “Lack-Of-Progress Report”, because the only information I can report is the fact that I didn’t have enough time to make any significant progress on the game over the past two weeks.

Here’s a video that explains the situation in detail:

Although the last “bug-fixing update” was uploaded on January 3rd, I continued to fix bugs after that date. I logged all of the bugs that I fixed into a text file on my desktop, but unfortunately, when my hard drive died last week, I lost that text file. I know that I fixed somewhere around 10 bugs, but I can’t recall exactly what they were.

So, here’s what this week’s changelog looks like:

  • Fixed bug that would cause students to face the wrong direction and not sit down in their seats if the player arrived at school late.
  • Fixed bug that would cause a student’s “detection marker” to remain onscreen after that student had died.
  • Fixed about 10 miscellaneous bugs.
  • Added a new Easter Egg.

Yikes! What an embarrassing changelog…hopefully, I’ll have a much more impressive one on February 1st.

Please Stop






Would you rather have me spend my time typing out a reply to your e-mail, or would you rather have me spend my time putting new features into the game? Obviously, you’d rather see the game get updated, so don’t e-mail me unless it’s extremely important!

For the love of all that is holy, DO NOT e-mail me and ask me when the next update is coming out, because by making me read your e-mail, you’re reducing the amount of time that I can spend working on the game, and thus you’re delaying the next update.

Read this: Please Stop Sending Me Stupid E-mails!

And read this: E-mail Problems and Download Problems

And also read this: Things You Should Not E-mail YandereDev About


Also, please DO NOT volunteer if you have zero experience doing whatever it is you’re trying to volunteer to do. Just because you own a microphone, this does not make you a voice actor. Just because you’ve made an MMD video, this does not make you an animator. Just because you can scribble a stick figure onto a piece of paper, this does not make you an artist. Do not volunteer unless you have an impressive portfolio of previous work to show me.

These posts do not stop 100% of all stupid e-mails, but whenever I don’t have a post like this at the top of my blog, I get 10x the number of e-mails that I normally receive.

Should Yandere Simulator be re-named?

Depending on your perception of Yandere Simulator, and depending on what you think the game is supposed to be about, you might be surprised to hear this, but I don’t think that “Yandere Simulator” is the most appropriate title for this game.

I’ve put my thoughts into a video:

As usual, I’d like to ask the community what they think about my latest proposal.

Should I re-name Yandere Simulator?

How do you feel about the name “LoveSick”?

Also, just for fun:

Which of these is your favorite name?

The last time I polled the fanbase, I think I got a pretty clear picture of the game’s audience. However, I’d like to run those polls again to find out if Yandere Simulator’s fanbase has changed over the past year.

How old are you?

What is your gender?

What do you want the MOST from Yandere Simulator?

Those are the only polls that I’m prepared to create right now. I might want to poll the community on other matters in the future, but for now, that’s all I’ve got.

What’s next?

I spent the first three days of the month fixing bugs. Making the “Past, Present, and Future” video took several days, I spent several days getting my computer operational after my main hard drive died, and making the “Should Yandere Simulator be re-named?” video took several more days. Now it’s January 13th, which leaves me with about 1 day to try and update Yandere Simulator. (Since it takes at least 1 day to make an update video, I’d have to work on the 13th, record a video on the 14th, and upload it on the 15th).

It’s nearly impossible to accomplish anything significant within 1 day, so I don’t think you should get too excited for a spectacular update on the 15th. I’m going to try my best to implement something special that I think will only take one day to implement, but I don’t want to make any promises.

By the way – if you’ve been following this blog for over a year, you might recall that January 17th and January 19th are special days for me. I’ll be hosting a special event on Jan 17th and 19th. I’ll make a blog post with the details on Jan 16th. However, it’s completely unrelated to Yandere Simulator, so I’ll delete the blog post after the event ends.

By the way…

In my latest video, I prominently featured three indie games: Surgeon Simulator, Goat Simulator, and Shower With Your Dad Simulator. I used these games as an example of why the word “Simulator” is associated with humor. However, I wasn’t trying to imply that these are bad games, I wasn’t trying to imply that these games are poorly designed, and I wasn’t trying to shame the developers of these games. I’ve played all of those games, and I got a laugh out of each one of them! I’m merely trying to communicate the fact that I don’t want Yandere Simulator to be dismissed as a joke simply because it has the word “Simulator” in the title. I intend to spend the next few years of my life trying to make sure that this game has excellent gameplay and solid design, and it would be very sad if all my work goes to waste because of a word in the game’s title.

Yandere Simulator: Past, Present, and Future

It’s the start of a new year! In Japan, it’s traditional to visit a Shinto shrine on the first day of a new year. The extremely skilled Namie has created a gorgeous illustration demonstrating what Yandere-chan might look like on Hatsum┼Źde, the first shrine visit of the new year:

Because a new year has just begun, I feel like this is an appropriate time to reflect on the last 20 months of Yandere Simulator’s development, and then talk about the future.

I’ve created a YouTube video about Yandere Simulator’s history, its current state, and what remains to be done before the game is complete. Check it out here:

In the above video, I attempt to accurately estimate Yandere Simulator’s release date using math. The year that I arrived at was 2019. This is likely to be very disappointing to many people; I’m sure that most of you want to get your hands on the finished game as soon as possible, and don’t want to wait three long years to eliminate Yandere-chan’s rivals.

I’m not pleased with this estimate, either. I enjoy working on Yandere Simulator, but I wanted to be done with this game in 2014. This game has already eaten 20 months of my life, and I really don’t want it to eat the next 40 months as well.

I’ve been working as fast as I can – 12 hours a day, not taking the day off on weekends or on holidays – but despite the fact that I’ve poured so many hours into the game, one man simply can’t develop a complex game like Yandere Simulator in less than 5 years. It really hurts to spend so much of my time working. It hurts to not have enough time to play video games, watch anime, or hang out with my friends anymore. I haven’t even played Fallout 4, or watched the latest Star Wars film! It hurts to have tons of game ideas, and actually have the ability to create them, but be unable to create them because one project is sucking up all of my time.

Everyone who tells me “You should work less hours! You shouldn’t work on weekends! You should take vacations!” doesn’t seem to realize that if I were to do any of those things, the 2019 release date would get even farther away. Do you want Yandere Sim to come out in 2022? No? You don’t? Well, that’s exactly why I can’t take days off or go on vacations.

In the above video, I proposed three potential solutions that could reduce the amount of time it would take to release Yandere Simulator, and now I’d like to let you vote for the solution that you prefer the most:

If you hate all of those ideas and have a completely different suggestion, then you’re welcome to let me hear it in the comments below.

In closing…

The matter of Yandere Simulator’s release date isn’t the only issue that has been weighing heavily on my mind. There’s something else that I’ve been spending a lot of time thinking about, and it’s going to be the focus of my next video. That video should be coming out within the next few days. It will also involve a poll. I hope you’ll vote on it, because it’s going to be a very important issue.

Thanks for your time, and thanks for following the development of Yandere Simulator.

January 3rd Bug-Fixing Update

Yikes, the last build had some weird bugs! Here is a new build with some bug fixes.

To read a list of everything that was fixed in this build, scroll down beneath this beautiful artwork by Danny-chama!

  • It is no longer possible to put on new clothing in the locker room if you’re wearing a club uniform. (It may be possible in the final game, but not for now.)
  • If you become bloody while wearing a club uniform, you’re allowed to take off the bloody clothing in the locker room. The bloody club uniform will appear on the ground as a pickup. It will not be possible to change back into your club’s uniform for the rest of the day.
  • You can no longer equip gloves while wearing a club uniform. (It may be possible in the final game, but not for now.)
  • You can no longer change into a club uniform while you’re covered in blood.
  • Adjusted the text that appears if a teacher discovers the corpse of a girl who seems to have committed suicide (but was actually pushed off the roof by Yandere-chan) so that the text is accurate no matter what time of day it appears.
  • Fixed bug that would cause the player to slide along the outside of the changing booth when attempting to change clothes inside of the changing booth.
  • Fixed bug that would cause weapons and other small objects to drop through the floor of the Martial Arts room and land inside of the Occult Club.
  • Fixed bug that would cause Kokona to walk around holding a knife if Yandere-chan distracted her during her “preparing food” animation.
  • Fixed bug that would cause weapons and other small objects to fall inside of the mat and cushions inside of the Martial Arts room.
  • Fixed bug that would cause the “A teacher discovered a corpse” text and the “Police Investigation” text to appear simultaneously.
  • Fixed incorrect text on the sign above classroom 1-2’s doors.

By the way, guys – please remember not to report bugs that can only happen through the use of debug commands. You won’t be able to use debug commands in the final version of the game, so there’s no reason for me to fix any bugs that can only occur through the use of debug commands.

January 2nd Bug-Fixing Update

Oops! There were some weird bugs in the previous build. I’ve prepared a new build with some important fixes. You can download it here.

Scroll down below this gorgeous illustration to see a bullet-point list of everything that I fixed in this new build! (I only wish I knew the name of the artist!)

  • In previous versions of the game, when the schoolday ended, Yandere-chan would drop all weapons that she was holding. If the player had committed murder, but had not been witnessed, had cleaned all blood, had disposed of the body, and had disposed of their bloody clothing, but had a bloody weapon in her possession, the police would still be called at the end of the day. This makes no logical sense, because there is no reason for Yandere-chan to drop a piece of incriminating evidence on the ground if she had successfully gotten away with murder earlier in the day. I have adjusted Yandere-chan’s behavior so that she will no longer drop weapons on the ground at the end of the day; she will simply bring the weapon home with her, which will count as disposing of the weapon. If the police are called to school and Yandere-chan has a bloody weapon in her possession, Yandere-chan will not drop it, but the police will still find it on her person. As a result, you can now kidnap a girl without having to dispose of the syringe that you stabbed her with…as long as you didn’t commit any OTHER crimes, and as long as there isn’t any OTHER incriminating evidence around school.
  • Removed circular saws. You weren’t supposed to be able to pick them up yet. They will be re-implemented once they have functionality, and/or proper animations.
  • Fixed bug that would cause an unconscious girl to teleport to the classroom beneath her usual classroom when Yandere-chan attended class.
  • Fixed bug that would allow the player to apologize to a student, even if that student had not witnessed Yandere-chan doing anything wrong.
  • Fixed bug that would cause two students to become unable to sit down at their chairs in the computer room.
  • Attempted to fix the “students get stuck and spin in circles when walking up or down stairs” bug.
  • Removed images of unfinished future content that you weren’t supposed to find out about yet.
  • Attempted to fix the “students get stuck when entering and exiting the changing booth” bug.
  • Fixed bug that would allow Yandere-chan to compliment NPCs more than once per day.
  • Did a better job of hiding the hidden girl.


PLEASE read the Known Bugs List before sending me a bug report! It’s a pretty big deal!

The Club Update

Happy New Year, everyone!

This gorgeous illustration from Noxina gives me an idea. I bet the sound of exploding fireworks could be used to mask a dying schoolgirl’s screams!

But enough about that; watch this YouTube video about the latest feature in Yandere Simulator: Clubs!

Clubs aren’t the only thing that’s new in this update. Here’s a full list of everything in this new build:

Bug Fixes

  • Fixed some incorrect text that would display during the End-Of-Day / Police Investigation text while the police were investigating a murder-suicide.
  • Fixed bug that would prevent a mind-broken slave from killing her victim unless the victim had stopped moving.
  • Fixed bug that would cause dead students to emit hearts from their heads while dead.
  • Fixed bug that would cause some “Student Info” portraits to be inaccurate.
  • Fixed skirt clipping and eyebrow deformation in the Cirno easter egg.
  • Fixed some more typos in the End-Of-Day / Police Investigation text.


  • Added 6 new hairstyles and 3 new accessories for Yandere-chan, and also two new hairstyles for Senpai-kun. These hairstyles and accessories were commissioned by fans of the game, and modeled by Druelbozo!
  • Added a special sequence somewhere inside of the school building.
  • Added a tool shed with a new weapon inside of it.
  • Added a hedge maze to the school grounds.
  • Added more props to the Occult Club room.
  • Added props in the Student Council room.
  • Added a garden for the Gardening Club.
  • Added 10 new collectible manga books.
  • Added two new easter egg modes.
  • Added props to the Art Room.
  • Added 5 new students.


  • A student who witnesses Yandere-chan commit murder will now refuse to speak to Yandere-chan in the future, and will damage Yandere-chan’s reputation on all subsequent days…until they die.
  • Replaced the copyrighted song that played during the “Sukeban” easter egg with original music.
  • Replaced the old small town test environment with a new small town test environment.
  • Examining the cheese now causes something to happen somewhere else in the school.
  • Changed the year that the game takes place in.


  • Club Leaders now wear a “Red Armband of Leadership” on their left arms.
  • Some clubmembers will now enter a changing booth and change their clothing before engaging in a club activity. This was only possible because of help from Saracen!
  • If the player speaks to a Club Leader who is in their clubroom, club-specific dialogue options will appear.
  • The player can ask a Club Leader for information about their club, ask to join the club, ask to quit the club, or ask to participate in club activities.
  • If the player asks to participate in club activities between 5:00 and 5:30, they will be shown a scene that features Yandere-chan participating in the club’s activity, and the day will end.
  • If the player reduces the number of students in a club to less than 5, that club will disband. The club members’ daily schedules will change, their appearances may change, and the doors to the clubroom will be locked.
  • If a clubmember witnesses Yandere-chan commit murder, but Yandere-chan is not arrested for murder, that student will warn the club’s leader about Yandere-chan, and Yandere-chan will be kicked out of that club, or disallowed from joining that job in the future.
  • If the player murders the leader of a club, that club will disband.
  • If the player quits a club, they won’t be allowed to re-join.
  • If the player takes an action that would result in a club disbanding (such as reducing the number of students to less than 5, getting kicked out of the club when the club only had 4 other members besides the player, or murdering the club leader) then the player will be shown a message at the end of the day in which Yandere-chan is informed that she has been kicked out of the club.

The Future of Yandere Simulator

I didn’t expect Yandere Simulator’s development to last this long. I think that this is a good time to make a video announcing how many features remain, how long it will take to implement those features, how I plan to carry out the rest of the game’s development, how I plan to secure funding, and how people can help me out.
