X-Change is a Japaneseeroge developed by Crowd and later published in English by Peach Princess. A remake of the game titled X-Change R was later released. It features new text by Soara Kisai and was never localized, unlike the original.
Plot
One day, while cleaning some shelves in his school's chemistry room, Takuya Aihara spills a chemical on himself and is transformed into a girl. The game has seven different endings; in some Takuya remains a woman, in others he returns to being a man.
Gameplay
Like most visual novels, the majority of the game is spent reading the onscreen text which represents narration and dialogue. The player makes various decisions at certain points in the game. These choices lead to different interactions with the multiple characters throughout the game.
