I really liked the music and the overall style of the game. The only thing I would change is a adding a Checkpoint-System, since I made it only to the 2nd axe part and had to start over, wich was a bit frustrating. But still a good game.
I hope you tried level 2 for this game. If level 1 is too difficult, you can use a cheat to directly go to end of level 1. See some of the replies from developer on my post below.
