10 Uncleared levels in 1 hour is a challenge I regularly attempt and this video features one full attempt. This is my first attempt at this challenge on the Nintendo Switch 2.
The timer in the bottom right counted down in real time as I played the levels. In Mario Maker 2, all levels must be beaten by the creator of the level before they can be uploaded. Apart from this initial "clear-check," none of the levels in this video had been beaten by anyone before I came across them. The levels were picked randomly from a set of older uncleared levels. No third-party tools (e.g. level viewer) were used to assist in the beating of these levels while the timer was running.
