Jumping far enough away from Sonic screws up his homing attack under the stage and he'll plunge to his death.
Nope it doesn't work that way.
As long as Sonic's homing Attack is pressing against the ceiling before the attack occurs he will continously smack against it. The only way he will fall to his death is if he somehow screws it up or if you dgo down there and having the attack target you.
This isn't a true stall. You're at the mercy of your opponent, who can lead you off the stage however they like and score a free hit.
Staling is simply stalling. Basically anything that lets you stall in a place out of the way foran opponent can be considered stalling. Luigi ladder for example, you can hit an opponent that doesn't stop it from being illegal. Neither does Peach bombing the wall yet they are considered illegal stall tactics.
Being able to hit the opponent doesn't matter, especially since one can place themselves out of the way of the opponent and make it that much more difficult..
Whenever Sonic bounces off of a ceiling doing HA, he either goes slightly forward, or toward the opponent he was homing onto.
Not really. While he does targe the opponent the direction in which he moves is influenced but only if it is a strong one.
For example if the opponent is still within HA range but is to the far right once Sonic bounces off the ceiling the momentum pushes him to the opponent However it can also bounce him to the left for some odd reason.
Make sure that you're letting HA charge and actually run into the ceiling. More often than note, if you cancel it, you cancel it before it touches the ceiling and it acts like a normal HA.

What do you mean Tenki the HA doesn't behave any differently. The attack box covers the entire ball. So when you're rubbing against the ceiling its the first thing you hit.
