I just finished playing it and I think it's a really great concept. Good job, man!
I have the same basic issues as everyone else. You should definitely speed up the main character, and change up his animations a bit to make it more apparent that he's moving. Anti-aliasing would make it look about 100% better. With a good amount of content development, polish, and programming, I think this could turn out to be a really fun game. Good luck, and keep us updated!
