Who Says Sprite Movies Have To Be Crap?
'Cause this sure as hell isn't!
I know I couldn't see any glitches or choppy errors at all, not that I even know what the 16K limit you said about even is. Plus my computer is ridiculously fast so that may have something to do with it.
Every spriter I know would KILL for that 'Spirit Bomb' effect, literally. I also like the new Yoshi sprites used instead of the old SNES YI ones, much better.
Plus the Terminator-Vision that you gave Mecha Sonic is simply inspired! Pure class! You've made him the supervillain he always should've been.
To be honest the ONLY problem I have with thise series is the plotline, it being nigh-on directly taken from DBZ. This quality of animation with an original plot would be sprite-nirvana.
Keep 'em coming Alvin!
