I absolutely love this game. The gameplay is great, the dash of stat raising is just enough, the animations are awesome,  the opposed love and kink routes for each girl are an astounding idea (and, oh, the kink route for Sarah... yikes!), and the ability to earn achievements is a nice touch that helps you know how much of the game you haven't yet seen. I'm still trying to figure out four of the achievements. I'm guessing they have something to do with the stats, but exactly how is beyond me so far. I didn't see anything in the guide about these four achievements, but I'll try looking again. But, wow, this game could keep you playing for days if you want to finish all the routes (and if you don't skip reading the text for each route).
