I like this game. But as a player (and a little as i'm a dev myself, not yet in dev but w/e) i would like to say that the loop for H scenes are disturbing.
You probably already know this but if the animation could loop smoothly it would be better (in my mind !). For sound effect, i can't say more than adding more variations but i know it's not that easy.
Anyway, i'm interest to see where it goes. Good luck for the next !
