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:
Customization
- 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!

First comment!
Good Job YandereDev! You did an excellent job once again. I hope you enjoy your vacation :).
And the people on the last update got upset because you only did bug fixes pfft but once they see this they can finally stop complaining how they thought you were scamming for money =_= some people cant be patient. Anyways, enjoy your vacation.
Great update 🙂
Awesome new update, have fun on your vacation! (And I’m really looking forward to female senpai! I love being a psycho lesbian.)
Have a great vacation! I’m still very excited for this game and looking forward to new updates. Thanks for all your hard work!
So like… whenever I select new or resume game I get stuck on a screen that says low school atmosphere and it won’t get passed that.
Yes,I tried to press any keys on the keyboard,but nothing happen.T.T
I had the low school atmosphere thing happen to me too.
Me too, isn’t there anyway to get out of this
I think he’ll definitely fix it once he’s back
seriously though, just imagine coming back from vacation as yandere dev, well rested and feeling great….
….and THEN discovering the Low Atmosphere screen of death
ı have it too :,( *cry*
Just tried, same problem here.
same here i hope it gets fixed soon……..
Same here! I was thinking of maybe redownloading it?
Me too :c
me too
yeah, its a bug. not just for a few systems, its for the whole game in itself.
me too !
Is there no method to restore the school atmosphere in this build?
BTW have a happy vacation YandereDev!
I think you have to wait day with no murders.
Yeah, that problem is happening to me too. I hope he notices before he leaves >_<
Gotta admit, you totally delivered YandereDev. Relax with your well-deserved vacation!
OHMYGOD OHMYGOD OHMYGOD! This looks AMAZING! I would have been happy with just a new accessory or something, but THIS? Yandere Dev. you are a god among men!

Lol.
This update was totally awesome and unexpected ! Fuck yeah ! You’re game is one of the best !
Did you actually play the update? Its stuck on the same Low School Atmosphere screen.
how can i fix low atmosphere title i want to playyy pls fix it
I LOVE this new update! Its adds a lot more personality into the game! Even though i cant play it because of the Low Atmosphere screen, I am very impressed with your work! I hope you have a nice vacation Yandere Dev! You need some time to relax for once, you work your butt off all day and night. Congrats to you!
I have some problems running the game.
Senpai decorating and uniform appearance of the decision only after the phrase ‘Low school atmosphere’ float can not do anything.
+ Communication uses a translator that not connote properly.
I have an issue, but I can wait until you finish enjoying your much deserved vacation. I will let you know the problem. After I finish choosing the uniforms and customizing Senpai and I go through the introduction, I cannot start the game after, I see a grayish screen with the words ‘low school atmosphere’ I will try and resolve it myself, just wanted you to know there was something wrong.
Enjoy your vacation YandereDev! I loved the video has well.
Oh my Dev please notice this awful bug, dont leave us!
Patch this bug and get good vacation, please!
[Statement] There is Low Atmosphere problem. [Request] Please fix it. [Best Wishes] Rest fine on your vacation.
SENPAI PLEASE NOTICE THIS BUG
Stuck on Low Atmosphere, can’t play, broken.
Please fix it before you leave! Thank you!
Same here! come on i wanna play!
“Why do people keep coming to school? It’s a video game – leave me alone.”
C’mon dev, this isn’t a hard one to handwave. Japan hates truancy. Done.
Finally! I made a better Yoruichi! Phew, that was some hard work.
It’s awesome! *.* Please, could you send it to me?
Will you make a Soi Fon?
my email – sarape@tlen.pl Please *.*
Sure! I may make Soi Fon and others in the future! I’ll send it probably tomorrow, as I’m busy right now. Sorry for the wait. 🙂
why I can’t open game when i’ve download it?
Please Devpai! Fix this ”Low School Atmosphere” Bug! We really want to play!
can’t start the game becase of the low atmosphere title :C
Why?
i want a small cafe near school where you can kill people. and pls fix the low atmo bugs
Why don’t you let the player go around barefoot? So you make less noise, and your footsteps will not be heard by others!
Also I have a question: Going around naked influences People’s behaviour?:)
Yeah, I agree!
It’s my birthday!
Happy birthday xoxo
I have the same low school atmosphere problem.
I would like you to fix it as soon as possible, but I also understand your situation and I hope you really enjoy these vacations and take some rest 🙂 xoxo
(Btw, great job creating this game, I’m totally in love with it e.e)
i cant pass the ”low atmosphere” screen when i start or resume game, what happens???
same here :(((((((
fix it before you gooooooo pleaseee?
Can’t play, “low atmosphere” problem 😦
The wait will totally be worth it.
And don’t forget to Nuclear.
It just says Low atmosphere.
What am I supposed to do?
Summon Shenron
Same here :T
Everyone including me has probably E-mailed YandereDev so he should pick up on the Low Atmos bug at some point, until then be patient and play the older build rather than spam the comments for goodness sake. Spamming the comments isn’t going to help in anyway so just be patient people.
Ok I’m done ranting have a nice day everyone. c:
I agree, spamming him with emails is the reason why one of his builds was late, remember that, everybody???
;-; i cant play the latest working build because i just got back from my holiday and didnt have my laptop there, I wonder if i can download the build and find whatever files causing le problem :L idk
So you think spamming him with emails is better? He made an entire video specifically talking about that issue and you likely just added to the problem. Spreading awareness here is for everyone and not just the dev. Who cares if for the most part it’s the same thing? People have every right to be impatient about this and at least now we know it’s a game-breaking bug.
i’ve got LOW SCHOOL ATMOSPHERE problem please fix it before you leave plssssssss
i can’t do anything only show that low school atmosphere and i can’t play D:
Nice work! This is looking very nice! Also, enjoy your vacation! You need it. Have fun with MGS5, I’m gonna be getting that myself!
I can get pass the low school atmosphere! >< you will not know what i did! hahaha! XD
How did you do that? ‘-‘
pic or didn’t happen..
tell.
me.
HOW!
She didn’t do it guys, she’s trying to get attention.
how did you do that? tell me please
i am a hacker kind of…. but the good one!
PLEASE TELL ME HOW YOU GOT PASSED IT! T_T
Can’t you guys see he’s a troll fucker trying to get the attention that he’s not able to get like a normal person?
Hay un error, cuando pongo para jugar la pantalla del juego se pone en rosa y no puedo jugar, i fix plis.
There is a bug when I get to play the game screen is set in pink and I can not play, I fix it plis.
The download seems to be broken for me. It won’t open every time I download it. Is anyone experiencing this issue, or is it on my end? I download the .rar, but every time I try to open it, I get an error that says “Can not open file ‘C:\Users\Azalea\Downloads\YanSimSeptember1st.rar’ as archive”. What could be causing this issue? Because for me, it seems the download is broken, but I don’t know if it is that or an issue on my end. Also, this still happens if I click extract instead of trying to open it, and I can open other .rar and .zip folders fine. It’s like this file itself is broken. It is broken every time I try to download it. Is anyone else having this issue? Help would be appreciated.
I think I had this problem before aswell
is there a chance the download got corrupted/interrupted?
if so try turning off you antivirus for the internet till it has finished downloading then turn it back on after and try it then.
If that doesn’t work I’m really sorry DX
Try using winRar archive decompresser. I had the same problem, so i used that to open it.
But with the new update, theres a bug that pretty much breaks the game, so keep playing/ download older versions of the game. I hope this helps.
Hopefully the bug gets fixed
why does every build i download crash right before i start playing, anyone know??
This build doesn’t work so your not missing anything… anyway… use winrar to unpack the file you download. Unless you’re trying to play on a mac, then there’s no hope for you.
i’m using winrar to do all of this but still nothing s happening, is there any other way to download the other builds??
