Okay...
Well, I'm reading through these other reviews, and they don't seem to get it. Yes, your decisions don't affect the game much, but that's because as a pacifist, you really don't have much choice other than avoid conflict. Go figure.
As for the game, I understood the concept and I actually thought it was humorous because as a reformed doormat, I totally know what she's going through. I especially liked how the other characters slowly become dirtier and more grotesque. It would have been fun if you could make the poor girl just SNAP, but that would defeat the message of the game.
