When Darbian first shattered the world record for the Super Mario Bros speed run (which he set), no one thought his time could be beaten. To beat the game in under 5 minutes meant getting everything perfect with no mistakes, there was no room for error! Of course, it hasn't even been a year and his record has been broken by one single frame.
Enter Kosmicd12 who, using a flagpole glitch in the first level, managed to shave enough time off to hold to new world record in the game! It's insane how people still manage to shave time off this game. See the incredible run below.
