Pretty neat game, for a piece of homebrew.  Four stages, the last of which requires you to run like a mad...whatever you are.  Still, a few things did disappoint me.  Fireballs didn't seem to kill the mini-tofu monsters.  Despite being in water, you could not swim.  Running was not always apparent, especially uphill and on certain surfaces where running seemed to do nothing at all to your speed.  And lastly, it was not made apparent until the second boss that you could shoot fireballs in diagonal directions.

Still, I'd give this a 4/5...
