Here is the full list of all 12 I Cant Escape: Darkness achievements.
I was consumed in the deepest darkness
I fell into eternal darkness
I was poisoned to death by a damn rat
I was killed by an animated cluster of vines
I perished eating a strange blue mushroom
I was crushed by a living wall
I was killed by an animated cluster of veins
I became a watcher, ever vigilant, forever trapped
I finally escaped! But was it worth the cost?
I cast myself into darkness, with all hope lost
Because simply escaping is not hard enough
I stepped out into the sunlight, the darkness left far behind
