Hi, I "main" Gigachad since i got the game, and sometimes i managed to do a tech with the run which made me run at super speed.
I don't know if it was an interaction with another character, i don't know if it's just a random bug.

It happened 3 times, and it was always when i activated the run (down b) in the air when almost touching the ground.

It surprised me and the people i was playing against, however i've been unable to replicate it willingly. I hope someone knows how to do it, and Sai if you read this, thanks for implementing the Armstrong skin
