So far as I can tell, it's nearly impossible to beat the game- I kept running into tons of softlocks. I got a journal item telling me I needed zombie brains, but I couldn't go back and fight more skeletons to get bone marrow because I'd somehow managed to glitch the game to not allow me to go back across the bridge. Then I restarted the game and tried again but I ended up with barely any health going to the next stage and kept being killed on one shot. Orcs are also extremely hard to kill due to their tendency to clump up into large groups.
