Setting well captured
The whole flash seemed to be perfect overall. The music totally suited the flash's theme, and the drawing was very casual with very smooth animation throughout the whole thing.
Although, maybe fighting a large ball with a smiley face inside of a large factory with a jack-in-the-box type handle on the side of it did look rather queer. Not that I scored you down on it or anything, it just got me feeling all feminin/childish, which I didnt particularly enjoy.
Nice flash, well done.
