Played docked with m&k, all low settings, 100+ fps at 720p, FSR was disabled.
100% with no issues
I was able to run through the main game and the 'Staff Only' DLC and attain every single ending and achievement without any issue. Tentacle ending glitch that others have encountered wasn't a thing here.
Appears to run great! Did a run through of all endings and didnt notice anything out of the ordinary.
There might be a small bug with the (SPOILERS) tentacle ending (I'm not sure the intended way its supposed to work) but I didnt find it impacted my overall experience of the game.
Works, but there is a bug with one "ending"
There is a certain "ending" (death) that gets triggered in this game for linux users in a way that doesn't happen for windows users. It's unintended and therefore frustrating.
SPOILERS AHEAD: you're supposed to get a warning when jumping around that you're not allowed to peak into other stalls. If you click "I can't be stopped" the tentacle spawns and kills you. On linux this does not happen. Instead, the tentacle just randomly spawns after you've jumped near the stalls, leading to frustration because you feel like you can't explore without dying. There is no warning message at all for linux players.
I only noticed the discrepancy after watching someone play it on youtube, and they never once had a random tentacle encounter without a warning.
The game is playable, but the bug I mentioned with the ending is something I would consider "significant" in that it impedes progress. Windows players get a warning not to do that or they'll die, linux players just die out of nowhere with no idea why. If you're reading this then you know about the problem. Now maybe you can avoid it and enjoy the game.
No issues at all
Completed all endings without any issues.
