Interesting, however...
It needs a lot of work. Allow me to offer some suggestions:
The animation is pretty good, but some areas had frame lagging like when mario's puff appeared after fireball, I suggest that you ease up on the blur filter or that you trace bitmapped the image causing the slowdown, the text was hard to read due to a lot of it being cut off the screen. To make sure everything is on screen properly, make a layer titled outline, and use the sqaure tool to make an outline of the work space, with out a color fill. With this there you will know exactly where the workspace size ends and thus avoid this cut off. Other than these things I can see no other problem. I will also suggest a scene selection menu, as it makes it easier to review the scenes the audience enjoyed the most.
Hope this helps, keep at it.
