So there is a WR run that took about 17 minutes in real time and only 2 minutes game time. How is that measured? I am pretty sure that it's 2 minutes in the game, and 17 minutes combined doing everything else.

game time is only time spent in the actual game. any time you're paused or in the main menu or the game is not launched at all like in those glitched runs, game time is not counting up

Thank you blazer!
