Very good rhythm game! I've got one small issue though: the UI in the level editor doesn't seem to work correctly for me. I don't know how to describe it properly, but the windows' content seem to just progressively get more cut off the further it is from the bottom left corner of the screen, and I couldn't figure out how to place notes either. Apart from that, the gameplay is simple and enjoyable, the effects are nice, and I can see a lot of potential in the game itself.
