Read the whole review, it will give some pointers on what you need to improve on.
It is obvious that you don't like any of the Megaman games. You need to be more realistic with the characters from them if you are going to use them. This is supposed to be funny, and I didn't find it that funny.
1) You need better dialogue
2) A twist would be nice
3) Be more realistic with characters (s.a. the bird guy gets beaten just by merely knocking into Tails)
P.S. - I am, in honesty, saying that you aren't doing that good, but you do have good ideas. Good ideas, poor execution in other words. If you improve in these areas, I think your flash movies will be improved. No, I do not hold anything against you for using sprites.
