Let's check in on the people speedrunning Super Mario while blindfolded
Speedrunners are smashing records for rushing through Mario games without seeing the screen

This summer’s edition of Games Done Quick, a livestreamed charity marathon where speedrunners try to set new records for beating games way too quickly, featured two players annihilating childhood memories of being pretty decent on the Nintendo by playing through Super Marios Bros. and Super Mario 64 while blindfolded.
It’s a trick that may seem impossible to those of us already flabbergasted by the kind of players who can rush through Mario games that lasted us years in just a few minutes, but the blindfolded subset of speedrunners have been around doing this sort of thing for a while.
The most notable recent example is a streamer who goes by Crescendo, who managed to beat the original Super Mario Bros. in 11 minutes and 55 seconds while wearing a sleep mask. A video of the feat shows off his method, which involves using fireball-assisted echolocation (like some kind of game-loving bat) and knowing the levels inside and out.
