It was a jump where you have to wall jump to a ledge and dash to another ledge that is just hanging down a bit. Then wall jump up. I couldn't consistently land on that ledge in a position to do the wall jumps
Oh yeah I think I know which one you're talking about (level 2b?), that one's tricky tbh. I was planning make it to where its easier to jump and wall jump up the second part after the jam.
