Have only played through the trail, so I can't comment on the full game:
with that in mind, however I found this game a huge irritation! I liked where I *thought* it was going, the graphics are awesome, the characters deep (for an H-game), and an actual plot with good writing... and then suddenly the main character starts down a path I cannot even conceive a real person even thinking of, much less DOING! Totally broke all immersion... and I just started getting more and more irritated with 'her' as she rationalized intentionally having a relationship with her manipulating (and rather thuggish) rapist when there was no reason to. It is one thing for a person caught or already in an abusive relationship but for one *not* to go after it?!?!

Hell, at that point her just deciding to go out and find a tentacle monster to molest for sex would have made more sense!
... oh, and (again, in the trial) while it is difficult, it is very possible to be victorious over her attacker/rapist (without cheating) when he lures her outside to show her his 'secret' technique - but the game treats it like you still lost. This leads to some very nonsensical dialog/actions and invalidates a lot of the follow-up - the programmer should have either allowed for victory or scripted the player's loss.
