Should've Saved for Later
I think there's some potential in this. Did you have a deadline? If not, I think you should have toyed with it more. Some parts of the animation, such as the flip, weren't half-bad. If you flesh out some more-detailed character designs over the bones, and add some unique bits to separate this from other typical "random fight scene" Flashes, this could be good!
Keep in mind that quality is better than quantity. If you can't work on it any more but it's not finished, set it aside. You might have new ideas and inspiration later!
(BTW, the NG Preloaders can take care of your "right click > Play" issue in a snap.)
