Nice game! In level 2 some of the bullet timings make the platforming a little too difficult, and I think you should add checkpoints where the musical notes are. Other than that it was fun and I had fun playing!
Fun game! Level 4 was way too hard though, Spent about 20 minutes on it and nearly rage quit. Level 5 also wasn't as strong design wise as the others. But awesome concept and the movement was fun and fluid!
