Neat little idea. Wonderful clouds, and very nice character portrait.
Would have liked to see my input "charging" up while pressing a button, to better keep track of how long I've pressed. And I think having a way to speed up the "charging" would eliminate some frustration.
I think I liked the first level the best - gave me a kind of QWOP vibe in the sense of making a normally extremely simple video game task much more complicated.
