Could be Better
It was quite good, the animation was mostly Smooth and the Bails + Blood were done well.
Few Pointers -
1. Get rid of Gradient Fills
2. More Detail for the Backgrounds
3. Use 16 / 14 bit sprites, the 8 Bit stuff diddnt look too good.
Also, it would have been better if insted ofjust having Megaman do the same 2 Things in the same Are each time, If maybe the First one was always a Bail, or just a Different Character.
Maybe a sort of "Horse" competition story or somthing.
Overall, it was good, but you have alot to do before you start reaching Good / Excellent Scores.
