Interesting mechanic, and interesting theme usage. I really feel that with the proper tutorial and some well made levels it could be a great puzzle game !

When you move towards a wall you already touch it blocks you, but it's the only bug i found.

Really loved the sounds ! xD

 At first I thought the game was just pressing up, then I got one more puzzle like. I failed half the time by blocking myself in, but still had fun with it. Theme usage 10/10 or 5/5 in this case.

Very creative use of the theme! - gives this one some pretty unique player movement. I like the sounds too. One suggestion - could you align the tiles to a grid? That would be neat.

I think you implemented the theme very well and it is a simple, yet intriguing idea. Overall an OK game!
