Im stuck on the part just past the 3 blobs in a row
In this area (and possibly others, but I managed to reproduce here twice) it is possible to dash just a teeny-tiny bit too late, the spike(?)death sound plays and your character miraculously hangs onto the side of the column. You are puzzled for a second, as to what just happened, but then shrug, jump up on the column and... collapse instantly.
It's a most amusing bug, I laughed so hard! :D
Wonderful game, the last challenge reminded me of the mountaintop of Celeste, rather unforgiving. <3
