There's a glitch that allows to speed up the whole game. Is it allowed to use?

the only glitches that are allowed are unintentional skips in the robtop levels. Speed glitches are not allowed.

Speeding up the whole game requires setting your FPS a ridiculously high value. We have an FPS cap, so no.

whats the fps cap

we do have the option to change the fps ingame now, wouldnt that count?

Glitch can be done without changing FPS

Can you explain how?
