I just alt+f4 every time even if I am not getting frustrated just cuz it's faster.
Funny as hell seeing clips made on PC where the player falls off a cliff and knows if they can quit out fast enough, they won't die (and sometimes this is also used to trigger wrong warps to skip shit, too) but they use the menus to do it and aren't fast enough. Just hit alt+F4. Instant quit. No menus. Quick and easy.
Unless that's against the rules of the speedrun category you're attemping? 🤔 It would make sense to disallow it just for parity with console players. Some categories also similarly disallow "zipping" just because it's next to impossible to perform on a console, since it's dependant on framerate being at or above 60fps.
