Just awesome: 5/5-10/10
Well balanced game, good graphics, very smooth controls.
Level and character editors add a lot to the game, and are just fun as the game itself.
On the humor side, I like how the characters names are generated when features from multiple chars are mixed together.
Only minor downside: small performance lags here and there (no I'm not on a C=64, it's not a NASA supercomputer either, but I still own a decent PC... :-)
Guess if you're thinking about an online multiplayer version you'll have to be paranoid about performances! :-)
