Long story short, the game was banned for content in very early builds and Twitch is unwilling to continuously review a game in active development, so Yandere Simulator is staying on the banlist until it nears completion. YandereDev has reached out to them to try and figure out what precisely is so offensive in his game that other Western games which ARE allowed lack, to see if it's something he might consider changing.
YandereDev's video explaining the panty-shot mechanic was flagged for inappropriate content.Banned in China: Some sites (well, one in particular) have not taken kindly to the game.The self-imposed Alphabet Killer challenge note killing everyone in the school in alphabetical order (popularized by Jay from the Kubz Scouts) was implemented as an actual challenge mode in April 2020 after Jay continuously failed to complete the challenge due to various difficulties in normal mode.However, in February 2016, he did take a fan's suggestion that Mai Waifu should have rainbow eyes and put it in the game, mostly to see if he could. He no longer accepts fan ideas due to being busy and too far along in development to consider radical changes to the concept.But because people argued that the game needed a " goth girl", he created one. For example, Oka Ruto wasn't one of the ten rivals originally.In fact, the game's concept and basic mechanics originated in a thread on /v/. Ascended Fanon: Early on in development, YandereDev accepted a lot of ideas from the fanbase, especially from the threads on /v/.As a further nod, in March 2017, Dev put a hairstyle into the game to let Yan-chan resemble the modder's avatar.
Sure enough, the October 2016 update build (which otherwise only contained a few bug fixes and ability to tweak settings) contained the first iteration of Pose Mode.
When a fan created a mod that allowed players to place and pose any character to create amusing images a "Pose Mod" YandereDev said he liked the idea and has considered including something similar in the final game.His YouTube channel lists liked videos, many of which are Let's Plays and other related works for Yandere Simulator.
Technically, this means Michaela voices all the female students, similar to Mom0ki mentioned below. The audio she recorded for Kokona's screams as she burns to death is recycled for all the other girls who can be killed by the flaming ritual knife and Ayano's demonic pyrotechnics. She also voices the side-game characters Kuudere-chan note ( not the NPC Kuu Dere in the main game, who does not speak) and Tsundere-chan from Kuudere Simulator and its sequels, as well as Beldere-chan from Yanvania. Yandere-chan), Ryoba Aishi, the Lust Demon, the Placeholder Club Leaders, and provides the screams of Kokona Haruka as she burns to death.
Accidentally Correct Writing: YandereDev has stated that Yandere-chan wasn't designed with any particular real life mental health issue in mind and whatever she could be diagnosed with is fictional, yet her condition has a lot of similarities with (the common interpretation of) Alexithymia.
