This is a weird one, even for Bill Wurtz.
Update 29/11/21: removed a lot of bad color swaps and a few weird movements, and added beats in the drier parts. This chart is still somewhat stinky (it's Bill Wurtz, after all) but at least all of the stink is fair.

Update 3/12/21: Updated per Programmatic's feedback (thanks Prog). Also cleaned a few other slight mistimings.
Update 11/12/21: More SSSO Feedback. Added a few beats, changed some post-slider patterns, simplified a couple of wiggly movements
That song was... interesting.
