Played it solo for a couple of days.
The idea of a procedurally generated coop dungeon crawler is good. I like that the zombie enemy can chase you easily around the level.
One time a zombie spawned right on top of me and attacked me instantly.
The wooden tube rooms are a bit weird for a fantasy mine.
I like how easy it is to lose a grappling hook if you miss a throw, will make for some funny moments when playing it coop.
I'll try playing this with some friends when it's a bit more complete.
