I play the game normally without using any glitches as I don't know how to use them. @jannik323, the only moderater who has ever verified my speedruns, knows that very well. But after seeing the speedruns of the toppers, I want to ask that how do we do that Glitched double jump?

@jannik323 Thank you.
