Shouldn't it be taken down from the leaderboards since he uses Maya Run and powers aren't allowed in that category?

I was playing through this game normally, preparing for a couple IL runs, but i discovered this little skip that skips a couple seconds at the start of the boss.

What you need to do is run to the full right of the arena and stand there, you need to stomp on the first barrel. once the second barrel comes, jump so that you stomp it at the height of it's leap and hold the jump button.

This skips the other barrels that you need to stomp in order for King Barrel to land, as it is the bare minimum to start the cutscene.

Hope this gets used in runs soon!
