Works with the latest Ubuntu
This is an update to my previous report where I had said the game freezes upon any TV scene. After upgrading my OS to its latest version (which was a major update involving a new Ubuntu base: from Focal Fossa to Jammy Jellyfish), I have had no problems with the game whatsoever.
This crash had also affected other games like PC Building Simulator. So glad that the resolution was just an updated OS!
Crashes during intro scene
Unable to play the game
Crashes in Intro Scene and any TV-Screen Cutscene
Unfortunately, there is a nasty bug that is causing the game to freeze and crash during the intro sequence, as well as other areas that involve a cutscene displayed on a TV screen (such as in Act 6).
I have tried various versions of Proton (Experimental, 9.0-3, 8.0-5 and 7.0-6) with no luck. Tried various video settings (resolution, quality, windowed/fullscreen, VSync, etc.), but the only way I could get past it was to play those parts in Windows.

Works great
Played the entire campaign through, twice. Never experienced any issues at all, just flawless - smooth graphics and excellent controls.
Severe framerate issues in Chapter 13
After ~2h of playtime the game got very choppy. Issue disappeared after a restart
The later half of Act 13 was very choppy, even with a restart. Right before the end the game crashed once. After restarting I could continue the game normally.
Smooth experience, aside from a few hiccups in loading zones and a particular segment in Act 13. Playable all the way.
Game ran for the most part buttery smooth, but it would consistently have a half a second ish stutter in-between rooms.
SPOILERS-SPOILERSIn Act 13, during a particular sequence where you see a bunch of black shadows, my framerate went from 100-120+ to 30 ish. It was bearable, since the sequence itself didn't require any puzzle solving and was quite short.
SPOILERS-SPOILERS
Some information about my setup: I am running Gnome 46.1, on an Nvidia laptop, with the entire xorg session being rendered using the Nvidia card. I also have my laptop hooked up to a second external monitor.
I purchased the game on GOG, which is why I can't say how well it works with Steam and Proton, but I find it unlikely that it wouldn't work there.
Fan spins up to max on Steam Deck and the performance overlay shows about 6-8 FPS. Main menu does not respond to controller OR mouse input, so you have to open the Steam overlay and close the game from there.
The game runs perfectly out-of-the-box.
The game crashed once, during chapter 13. Restarted the game, reloaded my save, and everything worked fine.
I played the game at FullHD, Ultra settings, manually limited to 120FPS. On average the game maintained 120FPS, very rarely dipping to around 60FPS.
Some text is a little hard to read.
TDP lock to 9W, render res 60%, settings to Medium
Certain texts are hard to read or unreadable due to subsampling, especially text on walls (part of textures)
Graphical settings get synced so every time you change device you have to adjust resolution, scaling and preset
Game fails to launch using default Steam compatibility settings (Proton 7), with an error about Visual C++ install. You will have to manually select Proton 8.0 in Steam game properties
Cap to 40 FPS
Game crashes at chapter 13, and resuming the save still crashes. I can't even finish the game :( Didn't crash any other time. Have tried multiple versions of proton.
I tried everything I can to make the game playable on the Steam Deck, but the game never launches.
Crashes at about 80% completion
Crashes halfway through act 13. Reloading the save returns the exact same crash.
Game doesn't seem to boot in "stable" branch. Haven't tested on "experimental" just hopped on straight to GE.
FRS 30 FPS 8w
Text can be small and setting Ambient Occlusion to higher than medium makes text slightly blurry.
When there are a lot of sparkling lights or lasers the whole screen can flicker. But I think that's just the unreal engine so nothing new.
Cloud save saves all control changes and even resolution options which must be changed everytime you change machine.
On all medium settings game works great. Setting Ambient Occlusion to high or ultra will result in some minor "sharpening" effect and text on in-game computers screen have some extremely sever ghosting effect. Stick to medium or low.
While it runs well even at the pre-selected settings the game consumes a lot of battery. Also to sufficiently cool the steamdeck the fan has to spin up quite a bit, so the steamdeck may become quite loud. I had no game braking bugs, except one video which didn't play, however the audio for the video still play so lore-vise you shouldn't be missing out on anything.
If you like Portal and similar games like Quantum Conundrum, you must play The Entropy Center. It's, simply, another gem.
Custom (community) levels do not work out of box, but there is a fix in Wine 8.7 (commit 8bba759156f2e0e8e89aae162c916d9620ea70d8). Neither Valve's Proton, nor Proton-GE include it yet. So, to get custom levels to work right now, you need to replace winhttp.dll in your Proton installation with the version from Wine 8.7+. If you have latest Wine installed in your system, you can just copy it from there, e.g:
cp -b /usr/lib64/wine/x86_64-windows/winhttp.dll ".local/share/Steam/steamapps/common/Proton - Experimental/files/lib64/wine/x86_64-windows/winhttp.dll"
Otherwise, i think, you can take it from any binary package from winehq.org.
Player made maps don't work, it never loads when trying to sync account's
The main campain runs perfectly fine.
Mod.io login doesn't work.
Mod.io doesn't work, still searching for a workaround.

Audio stopped playing after the game being paused for a while
The demo works fine. There is some stuttering when transitioning to a new area, and at the end of the demo the screen goes white and you have to force quit out of the game. Otherwise runs great!
Runs as smooth as a native title.
At some random starts the game wouldn't detect the controller. Tested with PS4 & XBox Controller. A restart of the game fixes it.
Demo: works fantastic out of the box
Had a few hick-ups at the start due to shader compiling. Waiting half a minute before actually playing solves this.
The game works perfectly.
I finished the game without any bugs, between 100-144 fps on high.
