UPDATE: Ahoyoo has confirmed that Trimming the Herbs was uploaded with TAS tools, meaning that The Last Dance was the final legitimate level all along! Congrats to kazeihinn on the Last First Clear! The journey continues in Super Mario Maker 2…
ORIGINAL POST:
Team 0% is attempting to clear every level in Super Mario Maker before the servers shut down on April 8. (New level uploads have been disabled since 2021, so there is no danger of new levels appearing at the last minute.) As of a few days ago, only a single level remains: Trimming the Herbs, uploaded in 2017 by Ahoyoo. (See also Ahoyoo’s original upload video.)
The level is short but extremely precise, requiring Mario to use Bob-ombs to precisely remove Piranha Plants and collect coins while navigating a tight space filled with spikes. There have been over 200,000 attempts so far! If you have a Wii U and feel like you might be a Mario master, this is your opportunity to pick up the final First Clear in Super Mario Maker history.
In theory there are unbeatable levels. With some updates Nintendo fixed glitches, hit boxes, etc. Usually, when you play a level that was uploaded on an older version of the game, you get the old behavior. But there was one update, which did not adhere to this, and which did cause some levels (designed with now fixed glitches) to be unbeatable now.
But this project isn’t about beating all levels, it’s about beating all uncleared levels. Since those glitch levels probably were beaten before the patch OR you might be able to play them on an older version of the game (if the server allows it), these shouldn’t be a huge problem.
