found a glitch :p
Oh and I think I know how you did it. Did you use a controller to give input while the game paused on spawn/respawn? If you managed to give input to whatever unity reads as its default horizontal axis then that could still move you while nothing else that required a button press could in that semi frozen state. Also because gravity was turned off, you could just float sideways until you hit max air speed and start the game like that.
