Personally I think the up B is great, becasue I also only play against other people.
But playing against other people, namely my brother, showed me a major flaw.
The Rock. It can be spammed to hell. Seriously. It's overpowered. I love the move, but when someone like my brother plays, it's unbareable because it's too strong.
It does decent damage and good knock-back. But it's too much knock-back an damage, maybe cut both those down. And maybe it could be quite a bit slower. Because currently you can just zoom around the stage hitting your opponent and since it's so fast it's impossible to stop you. And once you hit them, you can go back into the rock before they have a chance to stop you. So maybe make it so that you can actually hit them in the rock to break them out, because currently it really is too overpowered.
And also as I said before, you should be able to start the rock in the air and also end it by pressing a button whenever you want.
But really, I can't wait for V.02, it's gonna be amazing!
-EDIT-
Also an idea for the Side Smash, just the same as Marios real one, except instead of a firey ball, make star dust effects appear. That would look cool and work really well.
