how does the WR holder only has submitted one Attempt in total and has held the record for 6 years. submitted one run had it WR 6 years ago and never attempted to beat it again just showed up and left with no trace? seems weird

it was an insanely lucky run, there's no reason to try to beat it again. cookie clicker speedrunning hadn't really "taken off" 6 years ago (as far as i know) so there probably wasn't a lot of competition.

edit: if you go to his youtube channel you can see that he speedruns zelda games as well, just doesn't submit them (at least on that srcom account)

His run is from before Speedrun.com was even a thing.
