Microbugs when switching from full screen mode
On Proton version 5.0 and below the game started with a black screen with sound.
Sound crackling is the only annoying part, and that's definitely not gamebreaking. Could also be because my laptop's a bit underpowered.
Flickering when windowed mode first entered, but easily fixed by adjusting the size of the window.
Opening cutscene stuttered consistently, but the rest of the game was fine
Works well barring a couple of problems that I encountered which might or might not occur for others.
Game came up in fullscreen mode but the bottom edge of the screen was missing. After switching to windowed mode, then back to fullscreen mode, the entire screen showed.
Immediately after installing the game, during the initial run, In the first scene, after picking up an item off the ground, the game controls stopped working. I couldn't move or select anything. After restarting the game by clicking on the restart option the problem did not recur.
I stopped playing when I got to the irritating revolving wheels puzzle, so I was unable to see how well the rest of the game works.

Runs smoothly even on ultra wide monitor
Game works only with proton version 5.0-9 (actual latest proton 5-13.1 gives you black screen after loading level)
