Cool game! I loved the music and how the animations lined up with it. There are a few things I would like to make the game easier (because I am not skilled): checkpoints so I don't have to start all the way at the beginning, and more lives.
I would also have liked to see more variety in the type of platforms and enemies.
Please put your music in an autoload next time so that it doesn't start over from the beginning each time the level restarts.
