This was a really cool idea I liked it! The controls were hard to get the hang of but once I did I actually found it kind of easy, you can just stick to the walls and go around almost everything. I had a problem where once I got the 5th note to the 5th block in the first level it kicked me out with the level complete noise, but then anytime I tried to click the second level or play the first one again it would instantly kick me back out to the menu and play the level complete noise. I also wish that it restarted the level instead of going to the menu when you died. Overall though cool game!
