This year's Summer Games Done Quick is all wrapped up, but if you're looking for another exciting speedrun to watch, this world record-breaking blindfolded Super Mario Bros. run seems like a good place to start.
Speedrunner Crescendo posted a video of the world record run last night, with the timer showing that he managed to beat the game in 11 minutes and 55 seconds. It appears the previous record was held by speedrunner dodai, who achieved a time of 14 minutes and 46 seconds back in 2016.
This all sounds impressive on paper, but the run itself makes for remarkable viewing: at one point Crescendo has to accurately count down the seconds needed to run a sufficient distance before making a series of perfect jumps. He uses fireballs as an echolocation device, and is able to figure out his surroundings from the noise they make when hitting a wall. He also seems to break bricks to figure out his position.
