I picked it up and have been playing it. The first day, it seemed to run fine, but today I've been having a ton of trouble with it. I'm struggling to go 15 minutes without crashing, and when it does crash, Steam stops responding entirely until I reboot.

Edit: I can't explain why, but after checking my logs, whenever my computer full-crashes, it's apparently caused by bluetooth, despite not having any connected bluetooth devices. I've disabled the bluetooth service, and now the game only crashes to desktop. Small wins, I guess.

Another edit: I appear to have fixed my problem. I installed gamemode via apt, and added 'gamemoderun %command%' to the launch options in Steam. Haven't crashed since.
