KosmicD12 has completed his last “Any Percentage” speedrun of Super Mario Bros..
The Mario maestro has set multiple world records over the years (including a blistering time of 4:55.96 in 2018), but his most recent feat of crackerjack platforming might just be unbeatable. Using a combination of Warp Zones, glitches, and his own tip-top thumbs, KosmicD12 shaved a little less than half a second off his previous record, and finished the game in an astonishing four minutes and 55.646 seconds.
He then promptly delivered a short retirement speech and walked away from any future “Any Percentage” attempts:
“This is everything I have ever wanted to accomplish in this speedrun, and even a little bit more. It is still improvable but I am not interested in the ridiculous things required to beat this, so that’s history for someone else to write!”
KosmicD12 still plans to keep playing Super Mario Bros., but he’s looking for a new challenge today. He said he’d like to tackle some of the game’s other speedrunning categories, which he’ll continue to chronicle on his Twitch channel.
