Yandere Simulator is an unfinished stealth action video game by American game developer Alex Mahan, better known online as YandereDev. The game centers upon an obsessively lovesick schoolgirl named Ayano Aishi, nicknamed "Yandere-chan", who has taken it upon herself to eliminate anyone she believes is attracting her senpai's attention.

Plot and gameplay
The player controls Ayano Aishi (nicknamed Yandere-chan), an apathetic Japanese high school girl who has developed a crush on Taro Yamada, a fellow student often referred to as "Senpai". Over the course of ten weeks, a different girl will fall in love with Taro, becoming a target for Ayano to eliminate. The player has the ability to kidnap, torture, poison, electrocute, matchmake, befriend, betray, and drown rivals, befriend other schoolgirls, play small mini games, access a street where the player can earn money by playing a maid café minigame, spend money at shops to buy different types of items, and more.

1980s mode
1980s mode centers upon Ryoba, a teenage girl who has become obsessed with a popular male student named Jokichi. Ten rivals stand in her way and a journalist is watching her every move, aware of her homicidal tendencies. In order to prevent detection Ryoba must plan her moves out carefully. If she acts suspiciously or does not clean up after her murders properly she will gain a "guilty" point. She can counteract these by befriending fellow students and maintaining a good reputation. Ryoba is eventually brought to trial after eliminating her rivals; if she has collected more guilty points than innocent ones she will be found guilty and imprisoned. If found innocent she will kidnap Jokichi and keep him in her basement until he agrees to enter into a relationship with her.

Development
Yandere Simulator is developed by YandereDev, a freelance game developer identified as Alex Mahan and based in Temecula, California. He first pitched the idea on 4chan in 2014, and after receiving positive feedback, decided to begin development. Mahan has stated that the series Mirai Nikki and School Days were inspirations for the game. In order to work on the game full-time Mahan opened a Patreon account in 2016; he has stated that prior to this he worked as a freelance programmer. The project is currently in development hell since 2015, namely due to its "ambitious nature" and Mahan being burnt out consistently since July 2019.On March 1, 2017, YandereDev announced a partnership with tinyBuild that would help him polish, promote, and publish the game. On June 10, 2018, YandereDev announced that the partnership ended with the company in December 2017.

Demo
In 2020, the game's first demo was released along with Ayano's first rival, Osana Najimi.

1980s mode
A prequel mode named "1980s mode" was released in October 2021. This mode is a story mode that follows Ayano Aishi's mother, Ryoba Aishi, and follows the same storyline as the main story. The developer has stated that this mode was created to test the game's various systems. 1980s mode features VHS effects and a new soundtrack in order to differentiate it from the main story.

Critical responses
Content and themes
The game has received criticism over its content and themes, with the most common criticism centering upon the presence of sexuality and murder. In their 2022 doctoral dissertation Kristian A. Bjørkelo noted that some hearing about or playing the game found it transgressive due to the themes of sexuality and murder, while others took more exception to an update that allowed players to kill cats as a way of avoiding police detection. They further noted that Yandere Simulator was an example of a game that conflicted with "the idea that play is harmless fun, something that can be considered for children, a notion that can be referred to as the idealization of play... or the fallacy of play".: 11 Cecilia D'Anastasio, writing for Kotaku, covered the debug version in a 2017 article; she commented that the game had received criticism for "glamorizing suicide, bullying and Bipolar Disorder—allegations that I strongly agree with, despite the game's merits as simulator for sociopathy." D'Anastasio went on to interview YandereDev in the same article, who stated that the game "pivots on the archetype of an obsessed, violent stalker, rather than female stereotypes."

Twitch ban
In 2016 Yandere Simulator was added to the list of banned games by the streaming service Twitch. Mahan was a vocal critic of the ban, stating that Twitch never explained what prompted its addition to the list and that he would have been willing to "modify minor, innocuous things that were never meant to be the focus of the game, but I would not be willing to remove gameplay mechanics, remove core features, or change the focus of the game." He further criticized the ban as a result of "self-righteous ideologies".

Progress
Fans have voiced concerns over how long development of the game has taken. Mahan initially responded to these concerns with an announcement in March 2017 that he would be partnering with TinyBuild; this partnership ended in December of the same year.

Grooming allegations against YandereDev
In September 2023, following the allegations of YandereDev grooming a minor after evidence surfaced, several of the game's developers and voice actors, including Ayano's voice actress Michaela Laws, left the project. Mahan released a response taking accountability for his actions on September 25.
