Your Hardest Levels On SMM2

If you guys have Super Mario Maker 2, what are you hardest levels you've ever made.

I think my two hardest levels are

Spinning Trees
ID : R77-W38-DQF

Or

Harder Than It Looks
ID : 5XG-77K-PSF

Both of these levels are very hard, with them both having clear rates under 0.5%, however I am currently working on something that might be a bit harder. I would like to see your hardest levels.

I just uploaded my first troll level. It is the most recently uploaded level on my profile.

This level was very confusing for me and it took over an hour for me to beat! This is by far one of the best and confusing troll levels I have ever seen!
