hmmm... not bad I guess...
This is done in pivot yeah?
try experimenting with flash if you can get a hold of a copy. As for the animation it wasnt too bad, but it could of been smoother and some of the movements were a lil wierd,
like there was no build up for anthing it just happened, like if your gna try and jump real high you bend down low first then push, u dont just shoot up.
Work on making the moves more realistic... then just basic stuff like buttons, sound and music, which are easy to add.
