After coming back to this level with more experience, I could quite easily take the world record! The differences are: added a Bunnyhop at the start, a more straight Lightning Strike Cancel angle, and a Full Jump before rolling off the ledge near the end.

Now in cosmo's run he did the LSC at the wall to get undetected, but I figured out that you don't have to do that, which saves a bit of time! I also then do a quick Slide to finish it off! All in all it's a very solid but it can be improved with a LSC on the invisible platforms (right when you land on the first one you do it, but I only got it once). It isn't that easy but it is possible, so it's worth to go for in future runs!
