Works out of the box

When using 800p the Pause menu items can't be selected directly, you need to click left of them. Can be fixed if you play in 720p. You can only change the game resolution in the Steam settings of the game.
You need to set the Controller layout to the "Official Xbox Controller Profile".
I played on 60fps and everything on High except Shadows at Low. If you change Shadows to anything higher the game will have huge dips. You can even set everything to Epic and limit the fps to 30 or 45 and it should be stable.
Not a single crash.
It literally just works
No fuss at all.

Game runs perfectly without any issues. Arch Linux Manjaro

Worked as intended

Works, if you tinker with it enough, and if you're lucky to not encounter crashes in the process.
There is no proper controller support - "official layout" is just a convoluted KB/M emulation, which doesn't really do its job. It's much better to slightly adjust the standard KB/M template (bind a button for on-screen keyboard toggle, Shift for Sprint, etc.)
40hz/40fps
Very poorly optimized. Drops frames in some scenes even on medium settings, down to 20+ fps.
CTDs (needed to reboot the Deck as it was lagging and freezing after these crashes), Fatal Errors.
Be aware that at this point you may have already been tinkering with this game for longer than its entire playtime actually is.
Game works. Got all the 11 Steam achievements.

needed to install media Foundation, the script on github doesn't work as the download link in the script is broken, but you can download the file manually and then amend the script to point to the local file.
Despite installing Media Foundation, some in-game videos didn't work properly. I was able to complete the game but I but i wouldn't say its playing as intended.

Game is unplayable because videos don't work.
Videos are integral to the gameplay and they do not work. Also, I was unable to pick up the camera. I could hold it and look at it, but it wouldn't go into my inventory. If you can't take the camera, you can't proceed to the next room.

Game bound to crash on entering the 4th or so area.
After starting the game and selecting the menu "start the game" the screen becomes completely white. Move the invisible cursor to the lower left corner and make circular movements - the "continue" button will become visible - then the game starts. When you call up the settings menu, the cursor should also be placed to the left of the labels so that the buttons become active.

Like mentioned in another report, use the following commands to install media foundation to get videos to play in game.
export WWB=~/.steam/steamapps/compatdata/1218250/ rm -rf $WWB/* git clone https://github.com/z0z0z/mf-install.git $WWB/mf-install git clone https://github.com/z0z0z/mf-installcab.git $WWB/mf-installcab WINEPREFIX="$WWB/pfx" WINEARCH=win64 wine wineboot WINEPREFIX="$WWB/pfx" $WWB/mf-install/mf-install.shs WINEPREFIX="$WWB/pfx" $WWB/mf-installcab/install-mf-64.sh

Game will install, launch and run without Media Foundation DLL but one is unable to complete the final puzzle. In addition the background image on the main menu is missing along with those on the instructions page.
