Yandere Simulator is a stealth game about stalking a boy and secretly eliminating any girl who seems interested in him, while maintaining the image of an innocent schoolgirl. The game is currently under development, and a free debug sandbox build is available from the developer's official blog and website. The protagonist of the game is a high school student known as Yandere-chan who has fallen in love with an upperclassman known as Senpai. Yandere-chan cannot bear the thought of Senpai in another girl's arms, but she is too shy to confess her love to him, so she must resort to sabotaging his love life from the shadows. Once every week, a new rival girl will fall in love with Senpai. Each rival must be eliminated within 5 days, or else she will confess her love to Senpai, which will result in a Game Over. If Yandere-chan is arrested, expelled, or obtains a bad reputation, the result is an immediate Game Over. Rivals can be eliminated with lethal methods such as poisoning and electrocution, or eliminated with non-lethal methods such as kidnapping or matchmaking with other NPCs.
