Ignore zero's...
ok, if you don't use frame by frame... use shadows... Draw your characters better, and don't use the radial-stuff of flash... it looks better if you use normal colors...
Backgrounds! Sound... don't do ray-man style.. it has been done...
A Few suggestions.
First of all, you need to change his name. Zion is the name of the last remaining human city in the Matrix, so people will probably become confused, as I did. Also get some better sounds, and give the character some more defining features.
