(I have no idea where to put this, hopefully here is good)
I've been trying to figure out this trick for ages, but basically, whenever I see speedruns of this game with speed characters, I usually see them do a short burst whenever they do homing attack and from what I can assume it focuses horizontal movement and maintains momemtum?
I managed to do it accidentally while messing around in Pyramid Cave, and from what I managed, pressing B and A (something along those lines) made me do it after a few attempts.
For example, here's a typical homing attack:
Basically it covers sonic the entire time you thokked, and leaves a long trail which eventually you slow down halfway through it.
Here's the thingy I'm talking about:
The blue aura in Sonic's homing attack ends in a burst and usually keeps momentum, if not lets the player travel faster.
At least, from what I gather.
Can anyone elaborate on this?
