Route Grade Votings
Total votes cast 9
The deep dark dank rift is okay as far as the blocking boulder. The thin can escape via a through-route past a trap-door rocking block, the rest face a taxing exit right at VS 4c-ish.
Luckily I was thin enough to fit through at the top - although I did have to push the boulder over the top of the chimney to one side. Very claustrophobic with just enough space to breathe!
