Not a fan of the "Secrets"/chips difficulty.
I was in the post-game with everyone at 100 affinity and pregnant by the time I got the second secret, when their affinity boosts and such seem to imply that they're meant to be part of regular progression.
I'd also love if there was some nova post game content.
That being said, it has an amazing mix of porn and regular game play without sacrificing one for the other, or one getting in the way of the other. It has great porn scenes, yet would still be a good game without them, which is a pretty rare combination.
So yeah, glad I bought it, it's definitely worth it.
