Nice little game! The concept is simple, but superpolished. I loved it! Nice art and music.
I would add a little more challenge to first level of the game, as the only comment
Great job!
I agree the beginning is a little slow.. I think I should have started out with maybe just catching like 5 leaves to start and then get to the next level where the squirrel is introduced. I was trying to give the player time to become familiar with the controls.. maybe just a little too much time. :P
