A very well done horror visual novel (with some romance elements?). Be warned: it deals with a lot of awful subjects, including sexual assault, dismemberment, murder, suicide, emotional and psychological abuse. Not all of these things happen directly to the MC, and it's not all present on every route, but it's definitely the foundation of the game.

That said, if you like games with strong writing and stories, or unraveling underlying mysteries, or meeting and learning about complex characters, then I definitely recommend this game. :D
