It's fun.
Save as much HP as possible during the hold-and-stomp section, then recover your HP during the easy run section, and mash through the final bracket to clear with a bit less than half HP remaining.
If you can't enter the twist hold with full HP, the end is very tricky. But that hold is tough.
