Wow

Was this done exclusively in flash? Your production value is extremely high calibur.

Nice animation

You have some great drawings and animation. The only thing I can add is that your audio has some issues. The characters speak a little too quickly and their sound levels are a lot softer then the sound effects. If you can level off the volumes (to a more consistent level) you'll have a great product!

Suggestions

Get rid of the white background. Put something interesting but not overpower in the backdrop. Ad sound effects to the blows. Cut down the length- speed up the action. This is fight sequence. I also felt the ending was a little anticlimatic. Wario could work but get a little involved. That being said-I actually enjoyed it. I think with some tweaking and editing it could be pretty stellar. One of the better sprite genereated movies I've seen!
