You've got a really cool art style. It immediately sets the mood, the music immediately adds to it.
The gameplay was was a bit on the frustrating side for me. It took me too long to make the first jump on the moving platform. I felt like I'd made it, but then I'd hit a spike I hadn't seen.
I recommend using a sound scatterer next time for footsteps :) They're a little too same-y.
Overall you've got a nice little game. I'd love to see you improve the controls and levels! :D
