Not too bad.
I give this a 7/10.
My reasoning is because the stick animation was pretty good, smooth.
My only niggles are:-
The background isn't up to the same grade as the animation.
A few sound effects on the boarding and fall would have been nice. (I'm talking about the fall itself, I know there is an effect for the board hitting the figure.)
A replay screen would help imo. Rather than a loop.
Aside from that, A preloader would be kinda useless, due to the flash's small size.
Keep it up. :)
And I look forward to hopefully reviewing more work from you. :)
