This video features noskip super expert endless from Mario Maker 2. Super expert is the most difficult official difficulty category as determined by Nintendo. Endless mode selects levels and typically allows an unlimited number of skips without any penalty and a finite number of lives, with a maximum of 3 lives regained between levels. Super expert, in particular, starts with 30 lives. I am opting to not skip any levels, regardless of what level is selected as a selfimposed challenge.
