It's really nice and colorful, love it!
Note: your game is HUGE, and it seems like a majority of the file size is from your audio. I checked the BGM folder and it seems you have two copies of each song (one m4a, and one ogg) - you should delete the copies that the game isn't using to cut down on the game size. I suggest you keep and use the m4a files since they're smaller compared to their ogg counterparts.
