So the last level, “Trimming the herbs”, has not been beaten. However the elusive creator of the level made an announcement that the level was indeed a TAS (tool assisted). Here is the announcement from the team 0% discord

WE DID IT! EVERY LEVEL IN SUPER MARIO MAKER 1 IS CLEARED! Trimming the Herbs was in fact a TAS, making ‘The Last Dance’ the final level cleared! Ahoyo published a statement regarding this which you can read here: #tth We ask you not to harass Ahoyo or anyone else over this and not cause any unnecessary drama. Keep the discourse healthy and rational.

@yamada_smm2 , who cleared ‘The Last Dance’ and with that the final uncleared level in Super Mario Maker 1, on March 15 2024, also earns the custom ‘Last Choreographer’ role.

A HUGE THANKS to everyone who was here from day 1, to everyone who cleared a level, routed a level, or just cheered us on! This is gaming history, and YOU are part of it! GRATZ!

Additionally, here is Ahoyo’s statement on his level:

TTH was made to be unreasonably difficult and to cause a ruckus. I put effort into promoting it in 2017 so that it could be played, dissected, and scrutinized. Once that would happen I would announce that TAS existed for SMM. I did not expect that it would go unnoticed or perceived as easy from watching the video, or that it would take nearly seven years to be uncovered. The sunk cost fallacy of wanting to follow through with the failed troll, combined with new IRL responsibilities, allowed the nonsense to continue. I knew about Team 0% so I let things be until they would uncover it. I delayed uploading bombs5 until the uploads shut down because bombs5 is also illegitimate. I deserve no credit for either, and will not deny Team 0% their victory.

From attempting to upload bombs5 I developed tendon issues in my thumb. After some breaks and noticing they weren’t healing properly, it became unrealistic to continue. Once I accepted this, I felt a sense of relief.

Someone had messaged me about a TAS they were working on for the Wii U. In a video they sent, it seemed to me like they had it working, but they told me they were abandoning the project. The TAS was replicated by my friend after two days of building…

Because I had already resigned to leave streaming and pursue other things, and suddenly had a working TAS, I thought that the bomb guy should go out with a bang, so TTH was constructed. The PogChamp contest was made because I wanted there to be a venue for kaizo enthusiasts to gather. The judges were doing a live viewing of the contest levels, and I let them know that I (intentionally) broke the timer rules and that after showcasing TTH, they should disqualify me.

The past week, when the time bomb finally blew up, things escalated quickly, and the community was divided, which was not my intention. I’m sorry for the drama it caused within the community, and I regret the ordeal, but at least it was interesting. However in the end the truth matters most. Congratulations to Team 0% for their well-earned achievement! SMM is cleared, and The Last Dance was the last level!
