Also Tails' spinning animation would have more frames because his animation is different than sonic and knuckles.
... No it wouldn't. The tails... would just use the same frames to flap.
I fail to see your point.
NO, his spinning is different. I am not talking about the tails should be in the same sprite!
I think it'd be best if they were a separate entity. Of all the angles to make, the side frames could simply be made with RotSprite, like NiGHTS Super Sonic. All they would have to do is pick a frame set (again, like NiGHTS Super Sonic) but based on the player's momz.
