I like this game :)
The artstyle is truly amazing, great and beautiful. Sprites are very great and detailed, Characters are very great, interesting and sexy :D CGs and backgroungs and UI are great, too. Plus music is very very nice.
Plot is very interesting. Maybe it's a bit simple and short but I think it's good this way. And it has replay ability, especially to see other endings. Choiches are meaning ful and each romance option has own route.
Edit: The "true" ending is truly beautiful. I've almost cried ♥
