Sonic smash a bust

Version 2.0
I was fighting as sonic, got the smash ball and used the final smash. First gotta say that the timer to use super sonic was maybe too long. Was playing a 10 stock match, I killed kirby 5 times with the attack. Also noticed that while being super, if you press down on the ground, you will get sonic's normal duck sprite, your not even super sonic when doing it. I was also able to pick up the assist trophy using this. Super sonic should also be able to go faster, fast enough so he is hard to contol. After the smash ended, it wouldn't turn back to normal sonic, plus I couldn't attack. I couldn't fly either, only jump. Then I got an ERROR
