Add music?
Not bad, I kinda liked it. It did have some flaws though, popped when I wasn't really near the clouds etc. Plus it would be nice if you had added some extra obstacles instead of just going up and down. (might just be that I didn't get that far) Just like that crow of yours which just popped me aswell. I also miss some background music.
All these things adds to the gameplay and the whole feeling of the game itself which I think would give you a better score.
