I'm not even going to wait to finish the game, I'm rendering my verdict right now. This is a masterpiece. Five stars, but only because I can't give it more than that.
(SPOILER ALERT) I got to the murder investigation and courtroom scene, and at first I was like, "What the fresh hell is this? I thought this was supposed to be a game about scoring with naughty schoolgirls! I didn't sign up for a murder mystery!" But fuck what I signed up for. It was INCREDIBLE storytelling. I mean, the writing here transcends a porn game. This is art. And speaking of art, the art in this game is literally second to none.
I have no criticisms whatsoever. Keep doing exactly what you're' doing, and don't listen to anybody who says different.
