This is me (AznKei) playing Yandere Simulator, an early build PC game made by Yandere Dev.
This is a sandbox game where you control as a character in 3rd person view nicknamed herself "Yandere". Yandere can use weapons to kill her targets but doing so would decrease her sanity, so she must eliminate her targets in more sophisticated ways. The player can upgrade her learning stats, equip an underwear that would give bonuses for her different actions.
Being a build, this game is far for being complete, so there's no ending yet as for 19th August 2016 build. But some elimination techniques are already being implemented such as kidnapping, fake suicide, homocide, poisoning, drowning, electrocution and murder-suicide. There's also some minigames like a short 2D platform game and reading mangas.
A girl nicknamed herself "Yandere" fell in love with her senpai, but they haven't met each other. She's also aware that other girls at the same school as her also fall in love of her senpai and she must eliminate them for being rivals to her. One person will assist her to reach her goal, even though they haven't met each other in person, the name of the mysterious person is Info-chan.
This game, along with the characters, sounds, graphics belongs to Yandere Dev.
