Well I see challenges all the time on the pixl forums... but never here. It originally started between me and Don but I want to see other peoples work too
So here it is. Just create a single action animated. Standing idle (idle, but not standing perfectly still if you know what I mean), punching, kicking whatever. If you want, go ahead and make a whole sprite sheet if you want, but you only need one.
I guess tho since there are so few that would actually be up to it it's pointless posting this anyway XD
