the amount of polish is 10/10. Really cohesive visual/audio style, great physics, very nice to play. Well done!
I wish there were some kind of lose condition. Maybe like a meter that goes down whenever you miss notes or hit the wrong colors, and cuts the song short if it drops to 0. That would've gotten me more involved in the gameplay and made me want to keep trying again and again to hit higher scores, or "beat" the song.
overall very well done for a 48 hour game! Very impressive
