A few improvements are to be made, but I think this is a good start. Specifically, the angle of the idle may be a little awkward to some people (I like it), and the crouch's proportions may need to be corrected a little bit. Let it be known that some sprites will be based off of sprites from this Sonic 3 AIR mod: https://gamebanana.com/mods/252834
Updates: V2 Added updated Idle sprites. Updates Scripts to reset animations upon the green flag being clicked. V3 Added updates Idle sprites.
