The challenge: clear 10 randomly picked uncleared levels from 2020.

Restrictions (March 2024):
Time limit: 1 hour
No skipping: 10 minutes
No tools: 5 minutes

Because there are only a finite number of uncleared 2020 levels, this challenge will get more difficult over time and eventually impossible once all levels from 2020 have been cleared. As a result, I will revise the rules of this challenge monthly as the pool of levels becomes more difficult.

The restrictions above were the ones I used for the attempt recorded for this video. In subsequent attempts (April 2024) the skip time and use of tool restrictions time limits were switched (10 minutes for tools, 5 minutes for skips). For this attempt at the uncleared decathlon, no third party tools (e.g. level viewer) were used and no levels were skipped. Typically I skip at least a few levels, but this level turned out to be a fairly lucky randomly picked set. Levels were selected randomly using knflrpn.com/mm2.

The attempt in this video occurred (and was livestreamed) on March 10th, 2024.
