The jump really sucks. After drop it should not bounce, it's really hard to control, it influences the fluency of the game. Think about that you want to jump continuesly, but actually you can't. You got to stop untill it bounce once. And the jump button should not jump continues while you press it. One press one jump, even if you are not release the key.
