Not sure how to beat the level where it says a "A plumber once jumped here". The left wall at the start without collision seemed like a clue, but couldn't finish it.
I'm sorry it's not very clear! You have to stack your loops to build a ladder, climb up, and then jump to the right to reach the portal.
Thanks a lot for your feedback! 🫶
Thanks, I did end up beating that level after sticking around for a bit more!
