great idea! but the animation is kinda wierd, i mean what if she got hurt in the air? will she be standing up doing that while she slowly falls back? or instantly zapped to the ground no matter how high up she was and then do that animation? anyway, i suggest you make a little animation where she falls back instead and have to get up, and like make her hp like 5 hearts (or batteries?) so she does'nt have to do the "knocked back" animation a million times (like she would if she had as much hp as megaman) sorry and.. yeah!
Once again, more clever ideas with this series. Just that little technique of changing the size/shape of the black and white silhouettes gives the whole thing a completely extra dimension and drives home the 'shock'. Where on earth do you come up with these ideas..
