k, I played this, now I comment.
Okay, after seeing this, I know that you can fix some things. When he climbs over the walls, why not take away his spindash, since his glide/climb combo let's him walk and smash through stuff? It's kinda useless anyway. The mimicking of Tails's running is cool (Where you need a pair of super shoes to go real fast, yo), so the frames would still be used there. I say use the falling frames for spinning when he goes over walls. That, or make him a kind of spinny-orb thing when he goes over the walls. I play SA2B, and he DID have a Spinjump, so you could do that here as well. It's an okay wad, and it combines Tails and Knuckles elements. The stats are well put together. Good job, but take the advice I listed =)
