For the sake of context, Sonic Boom has a bug where if you play as Knuckles and then pause mid-jump, he’ll jump again in mid-air. You can effectively use this to fly. The Game Grumps are using this exploit to its fullest potential in their playthrough.
Normally I don’t condone the use of glitches to beat a game but when the game is absolutely terrible and filled to the brim with glitches and you wanna show how bad it is, exploit as many glitches as you can.
