Had a lot of fun with this, couldn't help taking advantage of some exploits (jumping on top of clouds/sliding through them). I found a lot of spots where clouds could be jumped on in order to easily beat levels that would otherwise take longer. It is sort of nice though because it makes it more casual and leaves it up to the player.
I was surprised at the end, cool way to go about it. Impressive that you made the game so fast, the music was sweet and the cloud control thing felt unique.
