The “Alphabet Killer Challenge” Build

Well, well, well – it’s an update that isn’t a bug-fixing build, for once! So, what’s new in this update? To find out, scroll down past this gorgeous artwork by Sinnymonrolls:

A few years back, someone came up with an interesting challenge – “Kill every student in Yandere Simulator in alphabetical order.” It’s an interesting idea…but in practice, it’s actually quite frustrating, because of the limited methods for hiding / disposing of corpses, the tedium of cleaning up copious amounts of blood, and the frustration of not having more options for hiding your actions from witnesses.

As it turns out, the challenge is more than just a fun idea for a YouTube video – it’s a “stress test” that reveals which aspects of Yandere Simulator can cause frustration to the player. Even though it wasn’t an official feature of the game,  I found myself wondering what kind of tools could make this challenge more feasible.

For a long time, I’ve been toying with the idea of making adjustments to Yandere Simulator’s general gameplay to accommodate the challenge, but it was always very low on my priority list. Now that SNAP Mode is finished, I feel like I’ve earned the right to spend a brief amount of time implementing a small “just for fun” feature. Which leads us to…

The Alphabet Killer Challenge

While inside of Yandere-chan’s room, type “abcdefg” to begin the “Alphabet Killer Challenge”. The objective of the challenge is to murder 77 students in alphabetical order. Upon activating the challenge, the school scene will load, with several things different:

  1. 90 lockers will appear in the hallways of the school. Dead bodies can be hidden inside of these lockers so that you don’t have to worry too much about hiding bodies while trying to complete the challenge.
  2. A box of smoke bombs will appear inside of the Student Council room. The smoke bombs are infinite, but you can only carry one smoke bomb at a time. You can drop a smoke bomb by clicking the left stick (or pressing the “T” key on the keyboard). A smoke bomb lasts for 15 seconds. Any character inside a smoke cloud becomes blind until the smoke clears, or until they walk outside of the smoke cloud. Be warned – the smoke bomb is a double-edged sword, because it severely reduces your ability to see your surroundings clearly.
  3. An arrow will appear at the top of the screen. This arrow will point to your current target.
  4. A text box will appear at the bottom-right corner of the screen, displaying your current progress in the challenge, and naming your next target.
  5. The day will automatically restart if the police are called, or if you kill any student other than your current target.
  6. Your Physical Education stat will be set to “5” for this challenge so that you will have the ability to carry corpses.
  7. If you successfully complete the challenge, you will get a simple reward – something that I was originally planning to release as an April Fool’s joke.

Advice: If you get a stealth kill using a blunt weapon (like a baseball bat), your victim won’t bleed. It is strongly advised to only use blunt weapons and stealth kills when trying to complete the challenge. Using a sharp weapon for the Alphabet Killer Challenge is not advised.

If the challenge is still too difficult to be feasible for most players, even with the addition of the lockers and smoke bombs, I’ll happily take suggestions for additional tools that would help to make the task more feasible.

On that note…if the additions of lockers and smoke bombs feels like a massive improvement to overall gameplay, I can consider making them into official features that exist outside of the Alphabet Killer Challenge. (Maybe joining the science club would grant you access to chemicals that would let you make one smoke bomb per day?”


Fixes, Changes, Additions

  • Fixed bug that would allow student council members to get distracted by dropped weapons while in the middle of pepper-spraying Yandere-chan.
  • Fixed bug that could result in Yandere-chan being pepper-sprayed and sent to the guidance counselor’s office, simultaneously.
  • Fixed bug that would cause SNAP Mode to get glitched out if Yandere-chan walked through a metal detector while in SNAP Mode.
  • From now on, Yandere-chan starts the game with only one pair of panties available. The rest have to be unlocked.
  • There is now a lingerie store in town. You can use this store to purchase panties for Yandere-chan.
  • Fixed problem with Inkyu Basu’s portrait.

April 2nd Bug-Fixing Build

Oopsie! The last build had some bugs. I’ve prepared a bug-fixing build.

It’s important to mention that the latest build is currently only available from – the other sites will have it shortly, but for now, you have to use the Mediafire link to download it.

6th Anniversary and SNAP Mode Reveal

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:

  1. I don’t actually speak until 5 minutes and 15 seconds into the video
  2. There is a large emphasis on the project’s origins as a 4chan project
  3. Foul language is used (the word “shit” appears at 1:11)
  4. I acknowledge specific YouTubers
  5. 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)
  6. There is an unusual amount of emphasis on sexuality (the body pillows, the 18+ game crossover)
  7. The pink background that I normally use in all of my videos doesn’t even appear until almost 14 minutes into the video
  8. There are a total of three “Haha, the video’s not actually over yet” fake-outs
  9. The video is 17 minutes long, much longer than my average video
  10. 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”.

March 2020 Progress Report

I’ve got two conundrums:

(1) I want to routinely upload videos to demonstrate that I’m actively working on the game, consistently making solid progress towards my next goal, and regularly improving the game in meaningful ways. However, there are people who will be very disappointed with me if I upload a video about anything other than the release of Osana, and I’m not ready to release Osana yet.

(2) Producing a video can take multiple days away from development time, and right now, I want to focus the majority of my time on development only.

These two things have prevented me from releasing any videos recently. After thinking about it, I came up with a compromise: creating a short, simple, minimalist video, and uploading it with “Unlisted” status so that it can only be viewed by people who have the link. This way, I can provide a progress report to people who want to see what I’ve been doing lately, without notifying millions of subscribers or taking several days away from development.

Most of my videos take several days to produce, but this one was put together in less than 4 hours – writing the script, recording the narration, and editing the footage went by in a flash. Obviously, the production values are far beneath the standards of my usual content, but that’s exactly why it’s an Unlisted video for hardcore fans, instead of a proper video going out to millions of subscribers.

March 1st Update

I’ll keep it brief. Here’s a bullet-point list of good news:

  • I finished polishing Osana’s matchmaking elimination, and now the only Osana-related feature that still requires any polish is her Befriend/Betray elimination.
  • A very skilled volunteer has recently returned to the project after a long period of absence. With his help, Osana’s animations and cutscenes can look much, much better!
  • Recently, a fellow programmer with access to Yandere Simulator’s project files has been investigating whether or not there are any issues that would prevent me from being able to upgrade the game’s engine from 2017.3 to 2019.3. So far, while running the game on Unity 2019.3, he has experienced faster loading times, higher FPS, and no crash bugs. It looks like we’ll be able to upgrade to Unity 2019.3 soon, and then Yandere Sim will run faster for everyone!

While working on Osana-related features (and the feature I hinted at near the end of my Jan 1st video) I fixed a lot of bugs along the way, so I’m releasing a new build. Check out the changelog; you might find something interesting in there…

To see a list of all the fixes/changes/additions in the latest build, please scroll down past this chilling artwork of Yandere Sim characters as button-eyed dolls, illustrated by Koumi Senpai!

Bonus fact: This is crossover fan art, combining Yandere Sim with a game called Identity V! I think Koumi captured the aesthetic perfectly!

Valentine’s Day Update

On January 1st, I looked at the amount of progress remaining to be done before I could release the game’s official demo, and calculated that there was less than 2 months of work remaining. I planned to release Osana on February 14th – Valentine’s Day. Today is the day that Osana was going to be released…but it’s not happening.

Over the past 25 days, I’ve been subjected to the largest avalanche of hate and harassment that I’ve ever experienced. It’s several orders of magnitude worse than what I was put through in 2018, which prompted the Hate and Shame video. Every day, I consider making an “I quit, I can’t do this anymore!” video, because absolutely nothing is worth the amount of abuse that I’m receiving.

I was already morbidly depressed before this happened, but recent events have pushed me down to the lowest point I’ve ever been at. The severity of what I’ve been put through has completely killed my enthusiasm for the project and robbed me of all motivation to work on the game. It’s impossible to be productive under these circumstances. The only thing more difficult than finding a reason to keep working on Yandere Simulator is finding a reason to keep living.

The longest-ever gap between two of my videos was 50 days, occurring between the Live-Action Trailer and Guidance Counselor video. In 7 days, on Feb 21th, we’re unfortunately going to break that record. I’ll try to release something on March 1st, but I’m not sure if it’s going to be possible to find the energy required to make a video, when it’s already hard enough just to convince myself to get out of bed in the morning.

I fixed some bugs over the past couple of weeks, so I’ve uploaded a new build that is more stable than the last one. I’ll include a changelog later in this blog post.

On the bright side, I did get some cool fan art recently, which makes me feel a lot better. Here’s a really outstanding illustration from milkiii.tea:
