Very interesting concept
This is different, the controls and the idea are what got me. Well this is what it basically is, anyway :P
I like the art style. Kinda messy but its good. The colors you chose are a nice choice, green and white wouldn't have worked out too well :X
Its a unique game, and I really think that the absence of sound is actually a plus. Great work, and I hope to see more cool work from you. Totally awesome if you ask me! :D
