i dont know about that rolling input thing why not make a d>a in the rowing frames?
also about colour, i think you are talking about an old version of game maker. game maker studio can import sprite grids like a charm and you can use whatever colour youd like as invisible. i mean, like in gimp, you have a transparent background. its like that with game maker sprites.
edit:
@rhino.freak: dvz should be no problem about falling opponent hit: how about making that a new body type? so only special itr types will be able to hit it.
