EDIT: Found out that the problem was launching through the itch app. Following the instructions to launch the game via Steam worked like a charm. Works perfectly now.
I'm having a strange bug. After falling out of the vent, I get a "Now Loading..." screen when doing almost anything. Starting combat, walking to another room, or even just opening the menu. The screen seems to stay there no matter how long I wait. I'm playing on Linux (distro is bazzite).
