well i did manage to test the other beta, or the incorrect one, and everything seemed great except for the tilts, they didnt seem to really reach the computers and you had to be right next to them for it to hit. The Up B didnt really give any damage and didnt have any knockback. I think on the Down B (if you still are gonna keep it as the dig) he should come back up and hit a good amount. The smashes and the dash attacks in my opinion were really good. The throws were all great except for the back throw and the Up throw. The back throw you would see the animation throw the computer but Knuckles would appear back in the same spot from when he grab the computer. And the up throw animation looked weird after he threw them, he would just kinda squat or something. It was already mentioned about his second jump not really sending him anywhere. And maybe the up B special should go a bit faster since it seemed kinda slow. lol but that one is your choice.
Over all it's really good and i like his wait animation!

Oh and on the Neutral B special, If you use it in the air and you are close to the ground and you keep holding the B button, you'll throw the rock in the air and then immediately throw the rock on the ground afterwards. Just thought i'd point that out there if you wanted to fix that. Oh and for the down A in air, i think it should have a slightly bigger hitbox so you can hit people with it more. But other then that Great job SouthCraft.
