good foundation, potential to be great

This game is well built. The physics are great and the graphics are smooth.
The problem is the depth. You keep going and going, but theres no reward or change for anything.

Suggestions:

1. Change the backgrounds as the penguin progresses
2. There is a physics bug where if you hold the penguin at the right angle and keep jumping, you can literally never fall in. I think the air control might be too easy.
3. Give the player points for things like flipping in air (this is very hard, but possible and should be rewarded)
4. Add really high waves to throw the player off, but give them bonuses for surviving.
