One thing I will say, is this game DESPERATELY needs a Gallery. A main menu accessible one.
I mean, I think it needs a Harem route, too... I know I missed content because it does not have one, and whilst replaying the game a few times is not bad, I like all content to compliment not complicate other content :P .... but even if that does not happen... and I have to play through a few times, that will SUCK without a gallery to ensure I know where I am going.
