[Team 0%] 35th and 25th last uncleared SMB3 levels from 2020 (Super Mario Maker 2) 

Two fun levels.
The first one's main difficulty is figuring out the correct route. This was difficult because I couldn't practice (the online viewers don't show the correct direction of firebars, and I think I have to download one), but once I had that figured out, the level was mostly easy.
The second level is the one I'd say is more difficult. A lot of jumps are pretty precise, the hardest one being the controlled shell jump at 2:36. However, I got pretty consistent at it, and basically every other jump, pretty quickly.
Both of these levels were recorded a week ago, and now SMB3 is defeated in 2020. I beat one more level in the final 50 (the 16th last), but it was a 3 minute long puzzle, and considering a switch clip can only last 30 seconds, I'd have to make a lot of clips. Maybe I'll record this level with my phone in the future.
