Really Explosive Kung Fu

This is a game prototype about little kung fu guy who try to explore new form of kung fu, and that kung fu is really explosive.

Controls:
(gamepad highly recomendet)

left arrow - move left
right arrow - move right
up arrow - jump
space/(A) - punch
shift/(X) - roll

I will be glad to get some constructive criticism about the game in order to make it better.
