I downloaded the Windows version to make sure I had the correct sound.
The graphics are very cute. When she gets up to go out and comes back to her mirror, you only used a few frames, but the poses are so evocative that we understand the girl's intention, emotion, and character very well. Well done!
As for the game itself, I'm going to allow myself to be a little more critical. I love rhythm games, and music is super important. Your music is very pretty, but it's not in sync with the inputs required (at least, it didn't seem that way to me).
However, you've been clever with the SFX and camera movements that call for clapping or fist bumping.
The game is just a few centimeters away from being great, but I liked the atmosphere and the subject matter.
