In short, landing on an enemy's head kills them (usually, it does an assload of damage) and bounces you off ala the Mario games. This is done in a very hacky way, but it works well enough for a proof of concept.
KNOWN BUGS:
You constantly "stomp" on floors moving upwards.
You can "stomp" on inanimate things that don't die.
No new graphics or map, so no screenshot.
