Some interesting things in this entry, the evolutive movement mechanics gave it something as you had to adpt to your new physics on the change. Graphically I am not so sure where it wanted to go… the first background worked quite well for me, the moving leaves gave it a nice atmosphere, the evolution of the backgrounds had not particular reasoning I could follow and even though they look fine were not adding to the game itself for me as they felt disconnected to what was happening… if there was some kind of story or reasoning behind the transitions that would have brought consistence to things for me. Anyway an interesting experience, good job!
