You got the perk and are trying to make your way out?
There's supposed to be some kind of thingy where the perk is to take as a shortcut to the exit. I got so mad when I was backtracking and couldn't jump up. I suicided, and kept the perk, then I was equivalently happy.
I don't know, I must be doing something wrong - all I get is an exit that takes me to the cave entrance and I have to try to escape from the hellhole with my limited jumping skills. I've only ever seen one exit though.
Cave #3 that has done this - the screenshot is taken at the maximum jump height, so it's pretty clear it's impossible for me to get out. I'm getting addicted to these poison pills, haha.
edit: Patch notes for 0.703 say that this is going to be fixed in the next push, I'll wait until the release to continue so that my game stops generating buggy slices.
