Congratulations to HappyPiggy for taking back the world record! I'm happy that I checked speedrun.com when I did, or else I would've missed it. He first broke the sub 1 minute barrier, then just over 50 seconds, and then 48.9 seconds! My guess is that the feasible limit is somewhere in the 47 second range. I don't really have the motivation myself to give it a go at the moment, but I'm sure someone will step up and raise the bar even higher!
