Telekinesis Engine

This is an engine FlashChickBoom and I have made! I used his graphics for the weapons, platform, and character, although the character was animated (poorly) by me. He was supposed to animate it, except that I haven't been able to contact him, so don't even comment on the way he jumps. Another thing I'd prefer you leave out of your reviews is the size of the weapons compared to the main character. Right now the only thing we're really stressing is the engine, not the graphics. Oh, and sorry for the rainbow cursor. Any other color blends in with the background too much.

What we really need to know is if this is worth finishing.

INSTRUCTIONS:
WASD - Move
Mouse - Pick up and swing weapon
Click - Drop weapon
The damage you inflict is greater the heavier the weapon you're using is. However, larger weapons use up more mana, and higher mana also means higher damage. The more mana you have, the easier it is to move the weapons around.
