I can’t even tie my shoelaces while blindfolded, but some people manage to do some pretty amazing stuff without sight. Like speedrunner PangaeaPanga. This guy recently did a run of Super Mario World while blindfolded – and he did it in only 23:14.
I think he uses the sounds of the game to know what to do and when to do it, but I could never pull this off. It must have taken him a whole lot of practice.
