What... IS this?

In the meantime there is a community dedicated to taking every level that has yet to be cleared for the first time, and clearing it. Some of these levels take 6-10 hours of attempts to beat, and some of them use obscure glitches that no one else has discovered. Nevertheless, as of a few months ago there were less than 20,000 uncleared levels and currently there are less than 1,000.

Nothing remains but the most difficult platform experiences you can imagine. The community is confident they can "beat Super Mario Maker" but the deadline is fast approaching. It will be a tight race, and this is shaping up to be a potentially historic moment.

As of yesterday, all levels uploaded in 2016 have been cleared.

This image is the entire level. The end goal is at the red door at the right, which is connected to the red door at the top left. Meaning if you follow that little zig-zag upward to that door, you beat the level.

The level takes 17 seconds to beat. Or it would, if anyone but the level creator had ever beaten it.
