Something like 8/10.
The game is centered around music so there's plenty of that. The atmosphere is very lively, which I like. H-Scenes suck, too short, it was basically just a small addition to the game. This game is basically like KiraKira, so I automatically liked it even before I played it but at the same time, KiraKira was a great music VN masterpiece which set as a measuring stick. If KiraKira didn't exist, 10/10 Deardrops, but since Kirakira was so much better and this was pretty much 2.0, 8/10.
Shoichi the main protagonist was awesome btw.
