First chapter of the game is sweet and fairly innocent although (if memory serves) kind of confusing. That is where some versions of the game end. Which cuts out pretty much the entire game.
The rest of the game is a fairly bizarre story following unreliable narrators through traumatically fucked up scenes with a story that gets more and more twisted as it goes on. You have your drugs, brain washing, cults, delusions, orgies, death, and all sorts of things that could make people uncomfortable.
Wanna see a guy have sex with the desk of a girl he witnessed commit suicide? It's there! It's one of the tamer portions.
Still, for me, it was quite the experience. Not the best, but I don't think it deserves to be shat on.
