Nothing special, but well-made
I kinda wish people explained how they changed the setting whenever I see these Megaman flashes that can't really fit anywhere in the continuity. Well, this one doesn't contradict itself at least, which is a rare good sign. And there are hints of a real plot. Ooooh...
We'll see.
I don't know how much of the graphics were pieced together or modified rather than just pre-made, but the animation was smooth and fast paced, so it gets fair graphics score.
Sound was really good, with really well-matched music.
Interactivity... well, it had what it needed.
Style. Well, it had lots of that, even if not a very unique one. When I saw Zero doing the cliche shadowy eyeless pose, I expected him to also do the cliche "look up and reveal eyes before kicking ass" move too. Very disappointed that he didn't, lost points for that. :P
Violence... not much. I mean, yeah, it has generic robots getting destroyed en masse, but I still wouldn't rate that very violent.
It's not funny. Nor is it meant to be.
So there. Keep up the good work and I really hope the plot won't such when it starts to develop.
