Catastrophe

If you hit everything straight to manage your gauge until the final bracket bracket comes, it's manageable.

First 3 seconds of the last run is a pain but besides that it’s whatever

very weird brackets and awkward run

My feet aren't moving as much as I can see the end.

Basically, it's best to play the runs as if you're scoring for judgment, and the more you can maintain your combo by mashing, the more the perceived difficulty will drop.
