Oh I see, she was walking...
Took a while to realise that, just seemed like she was bobbing up and down for some reason...
Also, you say the backgrounds kind of sucked? I think it's more of a case that the backgrounds didn't exist at all; grey flat colour with a black box doesn't really count
The drawings were great, shame the legs didn't move about like the arms because just the straight up and down character flailing about looked a bit weird.
Also please, chase scene to Benny Hill theme has to be one of the single biggest cliches in animation history, I groaned by reflex when it happened... AND YOU KEPT THE CHASE GOING FOR THE ENTIRE SONG
1 point for decent drawings =]
