So in this game level transitions can only occur everyone 21 frames from when the game is turned on, and that might not mean a whole lot to you so I have very simple analogy that covers this and my chat has heard it many times, it's the "bus analogy". Imagine that this little castle that mario walks into, after completeing each level, is not a castle but a bus stop, and imagine that in the mushroom kingdom busses operate on a very very specific schedule such that every 0.35 seconds (which is 21 frames) a bus departs the station and takes its passengers to the following level and mario must ride one of these busses to get there, so no matter how quickly you play a level you must wait for the next bus to depart to get there.

[Mod Note]: This run was performed before rules regarding skin-mods were solidified. We decided to grandfather it in despite the use of a now disallowed skin-mod due to its removal having a negligible impact on the overall leaderboard. (2 Mar 2022)
