I was curious to see if the version of Mario 64 the Switch port uses had an alternative to the backwards jump stairs exploit and I found one on YouTube but holy crap its an ordeal. pic.twitter.com/pVBm6fNzy2— サムニーランド: Hungry for ヒムボー (@SammNeiland) September 19, 2020
Super Mario 64 speedrunners have been using the backwards long jump glitch to skip portions of the game for years now, but for anyone playing the game in the Super Mario 3D All-Stars collection, that glitch just isn't possible. That's alright though, as there's another glitch that gets you through the castle at a record pace, and it's even more impressive.
As you can see in the snippet above, it's possible to build up insane amounts of speed by wall-kicking consecutively in part of the castle. This glitch might take a lot more patience and skill to pull off correctly, but the end result is the same. Let the glitched speedruns continue!
