Wow! As of today, it’s been 6 years since I began working on Yandere Simulator! That’s remarkable!

A special occasion like this calls for a major update, so I’ve chosen today to release a big feature that people have been anticipating for a long time. How long? Watch this video to find out:
There are a few things that make this video very unusual:
- I don’t actually speak until 5 minutes and 15 seconds into the video
- There is a large emphasis on the project’s origins as a 4chan project
- Foul language is used (the word “shit” appears at 1:11)
- I acknowledge specific YouTubers
- There is a segment where I “break character” and stop using my usual “narration voice” for a comedy bit (at 11:31 into the video)
- There is an unusual amount of emphasis on sexuality (the body pillows, the 18+ game crossover)
- The pink background that I normally use in all of my videos doesn’t even appear until almost 14 minutes into the video
- There are a total of three “Haha, the video’s not actually over yet” fake-outs
- The video is 17 minutes long, much longer than my average video
- I don’t mention Osana at all
That last point is actually pretty important. If you’d like to hear my reasoning, click “Continue Reading”.
What The Hell Happened?
Even though an “anniversary” is often a joyous occasion, I’m not unaware that it’s extremely unusual for a video game to be in development for 6 years. It’s unfortunate that I am saying something negative on the game’s “birthday”, but the development of Yandere Simulator has been plagued with significant problems for several years.
I could write a dozen blog posts, each one about a different issue that has made Yandere Simulator’s development particularly difficult. I often ask myself, “What went wrong? How did things get so bad?” There are multiple factors that have contributed to the situation, each one independent of the others…but the one I’m going to focus on today is Osana.
The situation can be described with a timeline:
1. Over the course of 2014, Yandere Simulator was designed by taking suggestions from anonymous posters on 4chan. After having dozens of threads about the game, I compiled a list of every feature that seemed like it would be worth including in the game. This list was huge – it contained over 100 features. I underestimated how long it would take me to implement every single feature on that list. As we can see now, that list was long enough to provide me with several years of work.
2. For a period of 29 months (from April 2014 to September 2016), I was able to consistently implement major features in Yandere Simulator in two-week intervals. After implementing the “Matchmaking” elimination method, I ran out of features that could be implemented within a span of two weeks; all of the game’s remaining features required more than two weeks of work.
3. Up until this point, I was using the character “Kokona” as a test subject for all elimination methods. The last remaining elimination method, “Rejection”, would require the player to sabotage a series of scripted events. Kokona was a test subject, not a real rival, so creating scripted events for Kokona would have been a waste of time. Instead, I chose to create scripted events for Osana, the first “rival” of the game.
4. After 29 months of developing the game around a “video every 2 weeks” upload schedule, it was hard to break the habit. I felt a strong compulsion to prioritize the development of features that I knew I could put together within 2 weeks in order to create a cool video. I split my attention between Osana’s scripted events and other features (primarily essential mechanics, and occasionally non-essential mechanics).
5. From September 2016 until November 2017, while releasing progress report videos and implementing new features, I repeatedly assured people, “Don’t worry, I’m still making progress on Osana!” in almost every video. This was completely unnecessary, and ultimately did more harm than good. I inadvertently caused people to believe that Osana’s completion was imminent and that everyone should get excited for her.
6. In November of 2017, I released a massive 34-minute video where I demonstrated all of Osana’s scripted events. At the end of this video, I explained that I regretted placing so much emphasis on Osana in my previous videos, explained that the game was still missing numerous essential features, and announced that I was going to shift my attention from Osana to all of the other features that Yandere Simulator required.
7. A lot of people were still very impatient for Osana, and my comment sections were often dominated by people who were dissatisfied to see me spending development time on anything unrelated to Osana. Across multiple videos, I explained numerous times that there was no point in putting Osana into the game yet, because she wouldn’t be fun to eliminate until I finished adding all of the other features required. However, for a large portion of the audience, this message never really sunk in.
8. By the time we reached May of 2018, my comment sections had become completely dominated by people expressing anger over the absence of Osana, and I decided to address the matter directly. I released a quadrilogy of videos to explain the reasons for Yandere Simulator’s lengthy development and the absence of Osana – “Where’s Osana?” on June 6th, “How long does it take to make a video game?” on June 8th, “What’s going on with Yandere Simulator’s development?” on November 5th, and “Hate and Shame” on November 11th.
9. From then onward, I focused the majority of my time and attention on a “Pre-Osana Checklist” of all features that would be required before it would be sensible to put Osana into the game. While working on this checklist, I also occasionally made progress on Osana herself, although Osana generally only received about 5% of my time and attention.
10. As Anti-YandereDev sentiment grew stronger and the demand for Osana grew louder and louder, I made the critical mistake of trying to calm the fanbase by repeatedly reassuring people that I was still working on Osana and still making steady progress with Osana. Again, this was a massive error – it created the impression that I had been working nonstop on Osana without making visible progress, when in reality, Osana was something that I worked on occasionally in-between more important features.
11. Osana became “functionally complete” in the last days of December 2019. The reason why she has not yet been released is because I am extremely invested in producing a quality product, so I am dedicating several months to fixing bugs, removing exploits, and adding polish to the game before Osana is released. Osana was on schedule to have been released by now, but unfortunate events unrelated to game development severely impacted my ability to be productive, and threw me wildly off-schedule.
12. I am now in a position where, if I release any kind of content whatsoever, the feedback I receive will be “You should have been working on Osana instead!” even though Osana should not be considered a higher priority than creating a solid gameplay experience. For this reason, I have been avoiding uploading videos to my YouTube channel…but I came out of my self-imposed exile for the sake of the game’s anniversary.
If only I had made different decisions in the past, then perhaps people would see Yandere Simulator as, “A free game that is updated frequently and has been receiving cool new features since 2014,” instead of, “A game that doesn’t have Osana yet.”
It’s…frustrating, to say the least.
And that is why I didn’t even want to say her name in the latest video.
Fixes, Changes, Additions
The new build contains much more than just the addition of SNAP Mode; 2 weeks’ worth of additions have piled up. Here’s a massive changelog of 30+ improvements to the game:
- When you are a member of the delinquents and intimidate a student into following you, the game will not use the usual “low reputation makes students follow you for less time” logic. Instead, the lower your reputation is, the longer students will follow you for.
- The over-the-shoulder camera angle (accessed by opening the debug menu and pressing the “T” key) will now always keep Yandere-chan on the left side of the screen, no matter what direction she or the camera is facing. This was accomplished thanks to help from AMZE!
- As an experiment, I have added windows the school building that allow the player to see the plaza at the center of the school. This has a negative impact on the framerate, but if people really want it to stay, then it can stay.
- Fixed “Dead Alive” bug that would allow the player to freely walk around after getting a game over, if they were caught misbehaving by a student council member while peeking into Info-chan’s room.
- When adjusting the Settings, the menu now slides over to the side of the screen so that the player has a clear view of what their settings changes are doing to the game’s graphics.
- Fixed annoying audio bug that would cause the school bell to ring twice in a row if the player attended class very early, causing the day to advance two phases simultaneously.
- There is now a “How to earn points” prompt on Info-chan’s Favors menu so that new players can learn about the multiple different methods for paying Info-chan for favors.
- Senpai is now MUCH more perceptive than he was before. He will notice your bad behavior almost instantaneously. This makes him much more of a concern during gameplay.
- Fixed bug that would cause inaccurate text to display onscreen if the player got a game over during Mission Mode due to being caught by a student council member.
- Began to make various small optimizations all around the school that reduce the number of objects being rendered at any given time, improving the framerate.
- The “Class Soon” / “Class Now” notifications will no longer pop-up if the player attends class early enough in the day to advance two phases simultaneously.
- Fixed bug that would cause students to perform the wrong actions if they were splashed with water while returning a dropped object to its proper location.
- Fixed bug that prevented the player from losing reputation upon being spotted for trespassing in forbidden locations (such as the boys’ locker room).
- Placed curtains outside of certain clubrooms where the player wouldn’t realistically be able to look through one of the windows and see inside.
- Fixed bug that would cause a Phone Addict to magically re-obtain their phone if the phase of the day advanced while they were phoneless.
- Fixed bug that made the button prompt labels on the title screen appear blurry when the game was running at low texture resolution.
- Fixed bug that would cause a Phone Addict to ignore the lost phone on their desk if they were in the “Classtime” part of the day.
- Every female character now changes their clothing at a different locker in the changing room, instead of all sharing one locker.
- The framerate should now be smoother during animations where Yandere-chan is being apprehended by a teacher or Heroic student.
- Fixed bug that prevented some buttons from displaying properly on the prompt bar at the bottom of the screen in Yandere-chan’s home.
- Replaced the 5-year-old voiced lines that play at the Heartbroken screen with higher-quality recordings.
- Fixed bug that would prevent the clock from displaying as “8:00 AM” if the player arrived at school late.
- Fixed bug that prevented the Counselor, Headmaster, or Info-chan’s portraits from appearing.
- Yandere-chan’s presence in a student council meeting is now considered “trespassing”.
- Students will now react negatively to witnessing Yandere-chan trespassing.
- It is now possible to remove a bucket that has been placed above a door.
- Further improved the silhouettes of the rivals on the Student Info screen.
- Fixed bug that made a countdown timer appear above Nemesis’ head.
- It is now possible to kill Nemesis in the “Horror Prototype”.
- Replaced Saki’s hair model with a new one.
- Updated the nurse’s hair model.
- Added SNAP Mode.

First!
ok, now I’m going to read this thing. (SO EXITED!!)
I’m impressed and i can’t wait for your April fools video
Happy 6th Anniversary for Yandere Simulator!
Now to wait for bijuu mike to see this
Cant wait for that dude to make video out of this.
HAPPY 6TH ANNIVERSARY!!!!
I am so proud of you! You have no idea I am for you right now! I wish that Yandere Simulator’s TRUE FANS will read this because I have a message for them. There are many haters out there that will try to make Yandere Dev convince you that he is a bad person (though he isn’t). Now if yoh want to stand up for him do it in a peaceful way. If the person you are arguing with isn’t nice to you because you have different opinions,then don’t bother replying back because that person just doesn’t know what to do with his/her life and js just sad. I have so much faith in Yandere Dev and in Yandere Simulator! Once again,Happy 6th anniversary and wish you the best! ❤
OMG OMG OMG ! I was waiting for this ! Thanks for updating the game today YanDev ! I was so excited !
Good work! My mouth was wide open!
WHERE IS THAT DUDE
yan dev you did a good job for that , can’t wait fo the demo , i think it will be legendary because it’s by yandere dev hands!!!!
Yandere Dev, I’m so sorry to hear that such large members of the fandom (although i have no wish to call them that) kept bugging you and harrsing you on Osana. I’m so happy that you’re going about this logically and not just giving in to the fan’s demands and thank you so gosh darn much for this new update!
I would like to say a few things I’d like to see in the game.
So, I think you should be able to chose a gender to be as, (Male, Female, Non-binary) and the gender you are attracted to. Just a thought 🙂
He was thinking about that in the past. I don’t know if he thinks about that now. If so, you have to wait longer than that.
That would require a LOT of assets
Yeah, I really agree w you.
He’s said that he doesn’t find male yandere’s appealing in the past, so being able to choose your gender is unlikely.
This is WONDERFULL NEWS! I can’t believe you made all these changes, added snap mode and made a video about it! Love your work and hey, we all make mistakes…it happens. Love SNAP mode. Sharing lots of love and support. I can’t wait for your next development of Yandere Simulator.
Whoah !!! I’m French, sorry for my bad English 😂! So I want to tell you that I love your game, and this build is freaking amazing you put so much effort !!! Keep this, you’re a good guy !
outstanding work. you never cease to surprise your audience. snap looks just like what I imagined the game to have . a feeling of dread , of darkness. it brings me back to older games that were just as dark such as manhunt, hatred etc. I really appreciate the work you put in and not given up on your goals or project no matter what anyone says. never stop doing what you’re doing. you’ll always have fans looking out for you and some chick in new york always rooting for you. gracias
Thank you for your hard work yandere dav. and don’t be sad because of the comments
Good job yandev! I’m sorry the dumb ones are the loudest. we really appreciate everything you’re doing. ♡
This is so cool! I can’t wait to try out snap mode. You’re doing amazing progress on the game, thank you so much for making it
wow… so its finally here…
Thank you so much for working so hard for these past two weeks. I know that it’s not easy to make such big improvements for the game. I’m really exited and can’t wait for Osana. Take as much time as you need. It can’t be longer than 6 years… Right??? Anyways thank you again so much!
Greetings from Slovakia🇸🇰
Does this mean that after Osana, all the rivals will be released faster? Can’t wait!
Can´t velibe this is happening. I hope that the final demo is like a good game yo see in stores. Is it going to be free?
I am so elated that we can now experience SNAP mode. I have been following this game development since 2014, I even played a few debug builds back then. I remember when the biggest update was a new school layout… wow… I can’t believe we’ve come this far. I’m so happy to see how Yandere-Sim has grown and evolved into such a complex and dynamic game. Happy Birthday, Yandere Simulator
Okay, so let me get this straight, Yanderedev, you are an exceptional person !
I am serious and I mean it sincerely, when I discovered Yandere simulator, I was a child who didn’t understand a word of what you were saying, 6 years later, I am 19 years old and I understand English perfectly and all that thanks to you!
I grew up with your game, I followed EVERY update and EVERY Easter egg and I never once thought “where is Osana” because she will arrive when she arrives, it’s your game and it’s your characters so don’t listen to anyone else but you!
I don’t know if one day you’ll read this message but if you do, just tell yourself that there are people like me who are silent and admire you.
Happy Birthday Yandere Simulator !
Ps: sorry for the spelling mistakes and for my English.
Omg, you perfectly described me and my love to this game!
How did you knew exactly my love for this awesome game?! XD :3
Omg, I am in love with that game! Snap mode is even better, than I could imagine it would be! I want to draw a fanart, but I have too much work, hope to make something soon!
I CANT WITH THIS DAMN VDIEO IM DYING YAN DEV PLESSE ROCK HARD ABS AAAA XD
SAME XDXD
omg I know right ( ͡° ͜ʖ ͡°)
Thank you so so sooo much YandereDev for all you’ve done for this game. It hurts to see all the hate, judgement and all the nasty things said and done by anti’s and I’m so sorry you had to go through such a thing. Before this post came out, I randomly decided to check the site and catch up on what I’ve missed out and when I got the notification for the new video and saw the new update was out, I got so excited. Please try to ignore the haters and anti’s because this is your game and your pace is your business. Your fans really do appreciate all you do for this game and we really do thank you and hope you will finish this game whenever it’s ready. ❤️
Wow happy anniversary!
We love you sooo much!! ❤️ Please take care and don’t lose hope!
(★‿★) OMG FINALLY SNAP MODE REVEALED!!!! Where download of it?
You just update the game.. ;-;
Holy…..SHIT IM EXCITED.
YandereDev, the team at Red Barrels called. They saw SNAP mode, and they want you to consult on Outlast 3.
Also, the body pillows made laugh so loudly!
You are amazing
Hey Yandere Dev! been a fan since 2016! I wanna say that just keep doing what you’re doing and don’t listen to these haters. Do what makes you happy and take care of your health, that is most important. Your game will be released one day and you will be so proud of it, do what you have to do, much love xoxo.
Glad to see development continue. I was worried that the growing amount of yandev hate would keep getting to you.
They are a loud and vocal MINORITY. Most of us either A) have common sense or B) don’t care enough about it.
I know as soon as the full polished demo comes out, the game will regain the traction it has lost since around the time Markiplier made his videos on it. And I hope it’s something you continue to take great pride in, because you deserve it!
Keep up the good work. ❤
I would gladly wait another 6 years for Yandere Simulator. I love it soo much and Im so excited!! You work so hard delivering updates as fast as you can. We dont deserve you! ❤️
Another new Saki hair model? Wow, she’s really insecure about her hair, isn’t she?
Yandere Dev, this is wonderful! I was so happy as ever when I saw one of the reviews, at first I thought that this was a fan version, but no, I was very surprised! You did a great job no matter how much you worked on it, I’m very happy, this mod exceeded all my expectations !!) I look forward to Osana, I’m sure it will be grandiose !!) I have been watching the game since 2014 and I’m very glad that you are so far gone, happy birthday Yandere Simulator!
(sorry for my English)
Wow Yandev! Its amazing to see how much progress you’ve made despite all the chaos that’s been happening.
I’ve been trying to make a game myself, but its so difficult to even know where to begin with everything you want to add. Seeing how thoughtfully you are keeping Osana unreleased is really clever from a developing stage. You are a huge inspiration to me and definitely to others out there.
You are amazing and are taking on a seemingly impossible task- (Holy, making a game this complex is hard work for any team! And your doing it yourself!)
You are doing great, and be sure you take time for yourself. Self care is important and others who hold the same viewing as me also want you to be healthy and happy!
Happy birthday Yan Sim and I support you through and through!
(Only commented once before, I’m not even sure if this is the same account, but I do want to comment more in hopes that you see my hopefully positive message)
Wow snap mode looks awesome!!
What will you work next?
Aye Snap Is Awesome!! I do have a question though you suggested an expulsion snap, I thought that the guidance counselor would be invincible like you mentiojed in the lets examine persona video
Yandere dev may you please put a happy ending. replay yes or no
YandereDev! YandereDev! (Sorry for my bad english, im spanish)
First of all HAPPY 6th ANNIVERSARY! I’m really glad for being a really fan of this awesome game!!! My first version I’ve played of the game was the 19-03-2015 build!!! And after all these years, you’ve done a HUGE progress on the game. Im really, really, proud of your work and this update was THE BEST!! I can’t describe how happy it makes me feel know that you’re making a great family on this game. I want to tell you that I was in the old moments, and i’ll be in the future, after the game will finish. I really really love you and Yandere Simulator ❤ I know that the haters are trying to take you down, but remeber, we (your fans) are here, by your side and we all together will defeat them!!
PS: I love so much the Budo's and Oka's body pillowcase. Are they available for a limited time or they'll be always in the shop??
Sorry for bothering you!!
Happy 6th Anniversary of Yandere Sim!!!! 😆 Reading the list of things you wrote down made me feel bad for you. You can do it! Don’t read those negative comments and keep going!
The League Gothic font was not a good font for Yandere Simulator… It will soon be reverted back to Futura Condensed Medium font…
So worth the wait! There are no words to describe how amazing this is Yandere Dev, bravo:)
Mhm mhm, you can now take down water buckets from above doors and..
YOU IMPLEMENTED SNAP???
Also, Saki has a new hairstyle!
I’m one of the people who would ask where is Osana. Honestly this blog post is a better explanation than your videos hate and shame how long video game, ect. There’s a lot more things you want to do before releasing her and those stuff aren’t actually related to her but the quality of the game.
It’s true, a lot of people doubt you because you make promises. It’s good that you understand that and that the development is unusually long. It helps to not make promises. The frame rate is much better now btw and I’m glad you decided to stray away from the children in the community. I’ll be waiting for more updates. Best of luck.
YES! Im so excited and im screaming like a schoolgirl now!!! lol
“To end [Ayano’s] life, you must mash a button rapidly, representing the tremendous willpower required to take your own life…but if you don’t press the button, the animation will slowly progress anyways, meaning she eventually kills herself even if you don’t do anything. So I guess willpower isn’t actually required, it just makes things go faster.”
I like that you’re trying to imbue the QTE with more meaning than usual, but this seems a little…muddled. And framing suicide as something that takes willpower rather than something people feel forced to do when they’re in a really shitty headspace…something which accomplishes what she set out to do…
Look, I’m not saying I think SNAP mode should involve Ayano getting therapy for her overwhelming cocktail of psychological problems (though that would obviously be the happiest ending to her story), but I’m not entirely comfortable with how Ayano killing Senpai and herself is portrayed as a last-ditch effort to take control of her life which succeeds. That doesn’t feel like the kind of message I’d want to send to an audience if I were writing this game, especially when I considered that said audience is composed primarily of young adults, aka pretty much the demographic with the highest risk of suicide.
I’m not going to claim that one single game where murder-suicide is portrayed as an effective means of asserting control in a world where nothing is going your way would drive anyone to suicide, but let’s not pretend that our culture is otherwise free of stories where suicide is framed in similarly concerning manners. The more times someone sees suicide depicted as a solution, the more likely they are to consider it one for their own situation.
I don’t know how to change SNAP mode to be less…that. Off the top of my head, I guess you could make it more tragic and less…successful. I guess that’s what bothers me the most (botched mechanical metaphor aside); Ayano tries to deny Senpai to anyone else and avoid any consequences for her actions, and she literally cannot fail, no matter how much the player tries to avoid it. And, of course, the player is supposed to empathise with Ayano’s murderous/suicidal desires, and actively work to ensure she accomplishes them.
In isolation, a game/mode where the player tries to drive a character away from their suicidal impulses sounds like an interesting way to handle the subject; in conjunction with the rest of Yandere Simulator, where you’re guiding Ayano through her (usually murderous) plans to possess Senpai, it would obviously not work. So maybe a better solution would be a post-SNAP epilogue, a brief cutscene where the survivors of the school mourn Senpai without a single mention of Ayano, something to hammer in the fact that Senpai is still loved by everyone else and Ayano is still isolated and alone. Suicide didn’t change anything; it made sure nothing could be changed.
Plus, adding a nice little coda like that would be a more natural emotional endpoint than Ayano stabbing herself in the throat. You don’t end a story at the climax, you know?
You know how in horror games (like Dead Space for example) when your character dies it shows an overly long death scene of your character getting their arms ripped off or head blasted in? It is deliciously horrific but also unnecessary. The purpose for it being there though is to show the “What If?” scenario. Snap is “What If?” times 10. If yandere chan lost her fight for senpai she will kill him and than kill herself. But all of this is that whole “arms ripped off or head blasted in” scene. The difference is that it’s playable. It will never happen in the context of the story so there is no need to take it as if this is something a person should do when their heart is broken. Now if IS how the story ends, well then yea I could see the problem. But just as a “What If?” ending? It’s just a crazy and flashy thing to see Yandere-Chan do. Plus chances are after you see it the first couple of times you are never going to do it again since it is ultimately a waste of time and is just a cool side thing to see once or twice.
I do get what you’re saying though. Young adults are easily influenced and acting out the scenario is much different than simply watching it. And since there is no way for yandere chan to fail you can’t put in the idea of her having a moment to reflect her actions before she commits the crime. But for someone to be that easily influenced by video game means that they already had a ton of problems to begin with. I don’t think a killer’s idea of murder-suicide would be coming from a video game like yandere simulator anytime soon.
There’s a big difference: The horror protagonist isn’t complicit in being ripped apart and isn’t rationalizing their reasons for doing so. Ayano…is, and is.
You don’t need to explain why Isaac Clarke being ripped apart is bad, because he clearly knows it is. Ayano snaps because she is trying to take control of her life, and she literally can’t fail at what she sets out to do. So you do need something telling the player that she’s wrong, that she isn’t taking control of her life. That she’s just ending it. It doesn’t have to be overt, but it does need to be clear, and it needs to be present.
You know how in the Infinity War movies, Thanos provides a detailed motivation for why he thinks he needs to wipe out half the universe to save the other half, and nobody ever takes the time to refute his claims about the universe? Even though his plan is obviously flimsy? Well, that’s why you saw so many people saying “Thanos was right”; he was framed as (morally) wrong, and he is wrong, but the reasons why he’s wrong weren’t provided, so the audience came away with the impression that Thanos brought up a legitimate problem nobody actually solved.
Imagine if the logical response to this was not memes making fun of the Avengers, but violence.
