This game has a whole lot of potential. I love the theme, mechanics, and characters. Once it comes to Steam, it might be the first NSFW game in my library. I really can't say enough about it. Very solid.
If I have to come up with some sort of gripe, I'd only say I want more interaction between the characters (and the player). Probably in the form of events. I'd suggest maybe an event for the first time the player interacts with certain monsters or does specific actions. I feel like this would allow the characters more chances to express their personalities more.
But that's like, just my opinion man. Keep making awesome stuff.
