works fine for me and some others
Well, I tested it against Sonic.
Works perfectly for the main part.
But when Sonic transformed into Super Sonic, it froze after 10 seconds. (I was standing still)
I tested it again, but this time over Olimar, it froze for no aparent reason. I just stopped moving for a little while and it froze.
The problem could be in the standing animation. You know, the Wait.
Or, in the Final Smash.
