Nice game, well done!
If I could improve something, it would be the player capsule. It doesn't have to be anything complicated, I like the style of this game actually. You'd just have to able to see it's direction. A triangle, for example.
And of course, more levels would be nice. Maybe you could introduce another mechanic? Pushable blocks, ground that crumbles away from under you after you have stood on in. Be creative :D
I'd really appreciate it if you would have a look at my game as well, and be sure to download the smaller version.
