I am sorry for the lack of video as I don't know anything about technology, but I do know my fair share about this game. When you enter the sort-of fighting pit in the arena, there is a pretty narrow walkway followed by some stairs which lead to an opening to the gate that is closed until the announcer is done speaking. However, if you turn around after going up the narrow stairs, you will see the doorway which you went through which is oddly shaped. If you go to the left side of this doorway facing the exit to the fighting pit and you jump up the doorway a bit (this requires a bit of acrobatics but nothing too bad, I will get into that later) you will clip out of bounds and from there you can down-warp into the middle of the arena. This alone saves time waiting for the gates to fall, BUT you can also maneuver yourself up the side wall near the opponents gates and get over it to kill them from there. A great way to get your acrobatics up quickly to be able to perform the clip properly is to trigger the announcer to start speaking and as soon as that is done, go back down the stairs and get your character stuck against the wall-ceiling near the first stair. The best way to get the wall clip consistently is to jump facing the doorway then turn 90 degrees to your right so you're then facing the stairs that were to your right. Holding forward and left from there gets you pretty consistently out. I have a feeling this will save at least some time.

I am almost offended by how incredibly Lukkyz is at this game, and if anyone could put up a guide or put here a consistent method at getting the backwards momentum that Lukkyz got in his world record run, then I would be very happy

Is there a possibility that someone could make a video showing all the out of bounds shortcuts that are in the game? Or just shortcuts in general. I feel like I've looked everywhere for a list of shortcuts and can't find anything!

I found out how to beat this game with only one ice cream. You start off normally and finish the tutorial, but then you only get the "You Can Jump" Ice Cream (I tried this glitch without getting that ice cream and it doesn't work) you go to make a new level in the level creator building, then you can just automatically create the level and once you hit "start from spawn" or whatever, what you're going to want to do is click the options button twice very quick, hit back to hub and confirm, if you did it right, you shouldn't be able to move, you can ground pound to be able to move. For some reason, doing all of this makes you able to run through walls, so you can head up to the sun boss fight with only one ice cream. This could be a new any% category!
