This game is another nice surprise, characters are nicely wrote, renders and animations are good and the story so far seems interesting, choices seems matter too (at least that's the feeling I get with current build). I'm really curious how everything will turn out.
The only thing I can by picky is the time-frame, everything happen very fast (around 1 week in game) but it's always hard thing to do in VN... and it's still better that artificially making it longer.
Overall, great game, keep a good work! Can't wait how the things turn out (hope there will be happy harem end :P)!
