Music is great! And the art and concept are really cool! Although it was a bit complex and not too easy to understand, and the controls weren't too easy to use.
Thank you! Though it seems that the gameplay wasn't as intuitive as I thought. The basic idea is that you're supposed to use the gravity field to increase the momentum of the notes, then turn off the gravity field to 'throw' the notes at the enemies. I hope that makes it easier to understand :)
