The Last Build of Yandere Simulator that Only Contains One Rival

June 17th Edit: Did you encounter any game-breaking bugs in the latest build? If so, scroll down to the bottom of this blog post for some important information!

Yes, it’s true – at long last, the time has finally come! This is the final build of Yandere Simulator that only contains 1 rival. The next build of the game will have 10 rivals.

You might be thinking, “Is it going to be Custom Mode, where the player can designate any student at school as a rival?” or, “Is it going to be Endless Mode, where the game randomly generates students and designates some of them as rivals?” The answer to both of these theories is, “No.” However, I’d prefer to avoid giving out any further information, so that the big reveal can be a surprise.

It’s a bit difficult to predict how long it will take me to release the next build. I know exactly how much work will be required, but I don’t know whether or not I’ll run into unexpected problems halfway through the process that will make it take longer than initially predicted. Will it take one month? Two months? Three? I’d rather not tell you my estimate, so that you don’t get disappointed if it takes longer than expected. However, I already have all of the assets I need to implement what I’m planning, so I feel very confident that I will accomplish my goal in a timely fashion.

I always hate to go for long stretches of time without releasing an update or showing progress, because it leads to misconceptions that the game’s development has come to a halt. However, I want the “10 rivals” feature to be a surprise, so releasing regular updates/previews is not an option this time.

Potentially, I could release blurry screenshots and silhouettes of the content I’m working on, so that people know I’m still working on the game, even if they can’t see exactly what I’m working on. But, if the screenshots give too much away and spoil the surprise, then there wasn’t any point to keeping it a secret in the first place. So, this is something that I’m very hesitant to do.

I’d like to reassure my most important supporters that I’m still working on the game, while keeping spoilers and surprises away from the general public. One potential solution is to start posting updates/previews on my Patreon page. I’ve basically ignored and neglected my Patreon page for 7 years, and it feels like it’s about time I actually started doing something meaningful with it.

If I do decide to start posting exclusive sneak previews of upcoming content on my Patreon page, these updates would probably only be available to certain Patreon tiers. Currently, the only tiers are $1, $3, and $100. A new tier would probably need to be created that is higher than $3, but much lower than $100.

The people who donate to me on Patreon probably don’t want to see me get screwed over, so they probably wouldn’t leak my posts. However, there is still a possibility that someone might join my Patreon purely to leak everything. So, I have to consider that when deciding what price to charge for the Patreon tier that would enable people to see exclusive previews of upcoming content.

I’m considering the idea of bringing back the Trello checklist that I used to keep people updated while I was working on Osana. I could write a list of all my tasks – keeping any spoilers as vague as possible – and put a checkmark next to them as I complete my work. The problem is, since I’m deliberately keeping the nature of the work a secret, you wouldn’t really know if anything on the list is meaningful or not…until the update finally drops, and you get to see what I was working on the entire time.

Anyway, the bottom line is that today’s build is probably going to be the last build for a while. Because you could be stuck with this build for quite a few weeks, I decided to make sure that the build is as stable and bug-free as possible. I also included a new feature in this build that is, believe it or not, actually essential for the upcoming feature that involves 10 rivals being added to the game.

Crafting System

There is now a crafting system in Yandere Simulator! It is now possible to build certain items that were previously only obtainable through Info-chan, such as stink bombs, bang snaps, and lockpicks. It’s also possible to use the crafting system to make a new weapon that isn’t available otherwise, and to modify one existing weapon. (The modification is just for fun and has no gameplay application, but I still think that “just for fun” features have a lot of value.)

Currently, it is only possible to craft 5 items, but of course, more can be added in subsequent updates. For example, at some point in the future, I’d like to allow the player to obtain the chemicals required to make lethal/emetic/sedative/headache poisons, instead of relying on Info-chan for all their poisonous needs.

To craft an item, you must first obtain the materials for it, then take those materials to the Workshop. (It’s the room that is between the Gaming Club and the Science Lab.) (The Science Club and the Science Lab are two different rooms.)

There are a total of 11 craftable materials in the game:

  • Ammonium
  • Balloons
  • Bandages
  • Baseball bat
  • Hairpins
  • Nails
  • Paper
  • Paperclips
  • Popsicle sticks
  • Shards of broken glass
  • Silver fulminate

Where are they located? Well, to make this a little bit more fun, I’ll let you discover them yourself! Hopefully, it should be easy for you, since every item is supposed to be located in a place that makes logical sense for those items to be in. (For example, the bandages are in the infirmary.) (The balloons are the only thing that didn’t really have a proper place in a school, so they are the one item that may not have logical placement. I’m sorry if you have difficulty tracking them down!)

You might be thinking, “Why did you put this feature in the game? Did the game really need this feature?” Like I said above, this feature was actually an essential addition to the game. Why? It’s a secret! For example, maybe I’m planning a plot twist where Info-chan is abruptly killed at the end of Week 2, so it needs to be possible to obtain certain items even without Info-chan’s help. Obviously, I’m not going to spoil the surprise and tell you the exact reason…you’ll have to wait and see! However, I can promise you that, in the next build, it’ll be very obvious why this crafting system was an essential addition to the game.

With that out of the way, let’s move on to everything else that is different in the latest build:

Fixes, Changes, Additions

  • Fixed bug that failed to reward the player with the correct amount of reputation points after succeeding at the Light Music CLub rhythm minigame, but only if the player began the minigame with negative reputation points.
  • Fixed bug that could result in a student getting annoyed at Yandere-chan for being in their personal space and taking reputation points away from her…while engaged in a life-or-death physical struggle with her, or being drowned by her.
  • Fixed bug that would allow the “in the presence of Senpai” effect to occur even if Senpai wasn’t at school, by standing at the point in space that Senpai would have occupied if Senpai was at school.
  • Fixed bug that would prevent the emergency shower in the science lab from working properly if the player approached it while wearing club attire (like the Art Club’s smock).
  • Students will no longer re-position themselves along the path from Osana’s lunchtime spot to the girls’ bathroom in Mission Mode; that feature is meant only for Story Mode.
  • Fixed bug that prevented the game from acknowledging whether or not Yandere-chan had poison in her inventory, if that poison was brought to school from home.
  • Fixed bug that would cause the game to softlock if a student council member spotted Yandere-chan eating a student during the Hunger Mode easter egg.
  • Updated the interests of the Photography club, since they were all meant to have an interest in “Justice”, and some of them lacked that interest.
  • Made a few aesthetic adjustments / additions to the front part of the school. It’s uncertain whether they will be kept or removed in the future.
  • Fixed bug that caused Yandere-chan to slide backwards while performing an attack, if a wall was north of her position while attacking.
  • Fixed bug that prevented the game from remembering the player’s preferred draw distance settings when loading into the school scene.
  • The poison bottle in the chemistry lab is now marked as “Lethal Poison” so that the player understands what type of poison it is.
  • Fixed bug that would cause the guidance counselor to counsel a student on a day that a murder was being investigated at school.
  • In Info-chan’s “Services” menu, each of Info-chan’s services now have proper icons instead of just question marks.
  • Slight adjustmenst to titan behavior in Titan Mode to hopefully prevent titans from clumping up together so much.
  • Fixed bug that prevented the save/load function from keep track of which bugs had already been placed at school.
  • Fixed bug that caused a bucket of brown water to glitch back and forth between looking brown and looking blue.
  • Fixed bug that could result in Kyuji following Osana into the locker room when she was taking a shower.
  • Students should no longer be able to get stuck on doors when attempting to pathfind to the rooftop.
  • Fixed bug that prevented the player from being able to speak to Raibaru at certain times of day.
  • Fixed incorrect subtitle that would display if Osana was splashed with a bucket of brown water.
  • Fixed bug that could result in the number of weapons at school becoming a negative number.
  • Fixed bug that made the Martial Arts girls stand inside of their classrooms at lunchtime.
  • Fixed bug that would cause the credits to not play fully before ending.
  • Improved Mai Waifu’s “eye color cycles through multiple colors” effect.
  • Yandere-chan is now using the correct shader in the beat-em-up scene.
  • Added one new hairstyle for Yandere-chan.
  • Added props to the Workshop room.
  • Fixed typo in Umeji’s subtitles.
  • Updated student portraits.
  • The 2nd-place winner of the MediBang art contest is now present in the game, represented by a cute plushie doll found in the Sewing Room! The prize for the 1st place winner has not been completed yet. (The plushie shelf is now getting quite crowded, and will probably need to be re-modelled before further plushies can be added…)

Recent Interview

You’ve probably noticed that it’s exceptionally rare for me to do interviews. My last one was in 2017! It’s not like I hate interviews, or anything like that; I just prefer to spend my time working instead.

However, I recent decided to set aside some time for an interview on the Duel Screens Podcast. You can watch the interview here:

I had a really great time on the interview, and it made me feel open to the possibility of doing more interviews in the future!

What’s Next?

If there is a critical game-breaking bug in this build, I’ll silently release a new build without making a blog post about it, and post the changelog here at the bottom of this blog post. Outside of that exact circumstance, this is the last time I’ll release a build that contains less than 10 rivals. I’m not certain how many blog posts I’ll make between now and the release of 10 rivals, but I’ll definitely post an update if there is something noteworthy I need to communicate.

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

June 16th Update

Oops! Exactly as foreshadowed in the paragraph directly above this one, there was a game-breaking bug in the “Last Build”, so I fixed it and uploaded a Real Last Build. (Let’s just hope that there won’t have to be a Real Real Last Build, then a Real Real Real Last Build, etc…)

Because it would be weird to upload a new build with only one fix, I decided to comb through the game for any other lingering issues and polish the build a bit more, just to make sure that anyone who downloads the game at this point in time has the smoothest experience possible. As a result, I fixed around 20 bugs! That’s probably the most bugs I’ve ever fixed in a 24-hour period!

Here’s a list of everything that is new or different in the latest build:

  • Fixed bug that would prevent Student Council girls from going through the right sequence of events while pepper-spraying Yandere-chan if Yandere-chan switched to a non-suspicious weapon while a student council girl was running to pepper-spray her.
  • Fixed bug that would cause Student Council girls to fail to perform the pepper-spraying animation while spraying Yandere-chan, if they had been alarmed by Yandere-chan’s footsteps a moment earlier.
  • Fixed bug that would cause all students to always react to Yandere-chan as if they just caught her pickpocketing, if Yandere-chan failed the “sabotage Osana’s phone alarm” event earlier in the day.
  • Fixed bug that caused the game to incorrectly identify Osana as “murdered” if the player sabotaged 5 of her events with Senpai and then went home instead of watching the rejection cutscene.
  • Fixed bug that would cause the game to count Osana’s Thursday sabotage event as two sabotage events if the player waited for Senpai to react at 5:55 PM before leaving and going home.
  • Fixed bug that caused students to unsuccessfully attempt to return a dropped weapon to its original location, if that weapon was brought to school from Yandere-chan’s home.
  • From now on, if you exit the Class screen without using all of your Study Points, those Study Points will carry over to your next class session, instead of just vanishing.
  • Fixed glitch that would cause the emergency shower to recognize a pair of gloves or raincoat as valid clothing to change into after taking a shower.
  • Fixed bug that prevented the player from being able to report a corpse to a teacher if that teacher was currently inside of the faculty room.
  • Fixed bug that would cause the game to soft-lock if the player was caught misbehaving after finishing the delinquent beat-em-up minigame.
  • Fixed bug that would cause a student to react negatively to Yandere-chan if she activated Pose Mode and then stood near that student.
  • Fixed bug that would cause time to not freeze during a photograph if the player was exiting “Speed Up Time” while taking a photo.
  • The student council can no longer be alarmed by you when seeing you holding a weapon while crafting items at the workbench.
  • It’s no longer possible to visit the Demon Realm unless the player has enabled debug commands / easter eggs.
  • Fixed bug that caused the “paper clips” and “silver fulminate” 3D models to be swapped on the workbench.
  • Fixed bug that would cause objects to float in midair after they were crafted at the workbench.
  • Disabled grass during the Beat Em Up minigame, since it was causing lag for some players.
  • You’ll now see the name of the new plushie when you send Info-chan a photo of it.
  • You will now hear sound effects when crafting things at the workbench.
  • Fixed bug that allowed the player to clip into things in the Workshop.
  • The “Practice” menu no longer defaults to “Very Hard” when opened.
  • Improved / re-sized the Info-chan Services menu icons.
  • Updated the appearances of 12 characters; Beshi, Dora, Kiba, Meka, Seiyo, Homu, Tsubaki, Horo, Uekiya, Yaku, Kenko, Kuu, and Saki.

June 17th Update

Darn! Just as I feared, there were issues in the last build, and it became necessary for me to prepare a “Real Real Last Build.” I’ve uploaded a new build with further bug fixes. Here’s a list of everything that changed:

  • Fixed bug that would cause the “trajectory arc” of a thrown object (such as a stink bomb or a bang snap) to remain visible even after Yandere-chan had dropped a throwable object.
  • Fixed bug that would prevent the player from being able to pick up a box of bang snaps / stink bombs if the player dropped the box while nearby a button prompt.
  • Fixed bug that would prevent Info-chan from displaying a student’s info screen after sending her a photo of a student.
  • Fixed bug that would allow the player to craft things without actually having the materials for those things.
  • Fixed bug that prevented the “spawn a trail to your destination” feature from working.
  • Fixed bug that would cause the game to softlock if the player apologized to a student.
  • Fixed bug that allowed the player to clip into the two trees in front of the school.
  • Fixed bug that prevented the player from being able to enter Titan Mode.
  • Fixed bug that made it impossible to open/close the school gate.
  • Updated Dora’s hair texture.
  • Updated the game’s credits.

  1. When you murder Osana and her corpse is discovered, Senpai doesn’t go to school one day but when he returns, he look too…normal. In fact it doesn’t look like his childhood friend was murdered. What kind of friend is he ? It seems like he forgets of it in two days. Raibaru doesn’t do that…

  2. Small bug that caused a game over:
    I had a mind-broken Osana kill someone near Raibaru in the courtyard and then held ‘Q’ to react, however, even though this is a perfectly normal action that everyone else was taking, Senpai and one other student saw this as ‘weird,’ hence the game over(as the teacher ran over to Osana and the other girls corpse lol). Hope its actually a bug and not just me finding part of the intended code weird!

    • I think it would depend on where you were standing. If you were super far away from the murder, then the game probably didn’t register the situation properly.

  3. os botoes do debug não funcionam ja o ativei em extra mais nn funciona nn funciona a / , h, p, o e muito outros botoes do debug

  4. Yandere Dev, Yandere Dev. Happy birthday ❤ You're the best and thank you from developing Yandere Sim. Please take care, stay safe. You're fan from Mongolia with love

  5. There is a problem during the ABC CHALLENGE, when it’s time to kill the red hair gardener, Tsubaki, it’s not possible to kill her or even talk to her

  6. heyo quick question, was wondering if anyone could help me. I’m having an issue with the camera locking into a spinning motion at yan chan’s feet? I cant walk anywhere because of it and when i try to lift the camera it just goes back to her feet. Help? Yes, I’ve tried deleting and redownloading the game. It fixes it temporarily.

  7. Sometimes i will socialize with a student and instead of just raising or lowering my reputation normally it wont stop. For example, I socialized with Raibaru and my reputation wouldnt stop being raised till i closed the game.
