Works without any issues.

Very stable with Proton
No issues so far - 3.5 hours in
Flawless out of the box.

Works without issues out of the box.

I was able to install and launch the GoG version through Lutris, but needed to run Proton Experimental instead of the default because it did not render anything.

Ran perfectly. I got all the achievements on Deck.

Game assumes my secondary, 9:16 monitor is the primary display making the game impossible to play
I cannot get the game to not assume it is running at 9:16 instead of 16:9, do not buy if you have non-standard secondary displays

After resolution of an issue in pre-3.6 Steam OS, game is working well. No issues with Proton and this game.

Some may experience issues with the game due to this issue that is scheduled to be resolved in SteamOS 3.6. https://github.com/ValveSoftware/SteamOS/issues/1257
Using most recent Steam OS and Proton on Steam Deck, game will start but will crash shortly after menu opens.
Plays like a native title
By dropping down to 45fps (@ 90Hz), I could lower the TDP limit down to 6 watts and reduce the GPU clock frequency to 600, which gave a projected battery life of 6 hours at just over 50% screen brightness.

Game ran out of the box perfectly.

GoG install files installed via Lutris
Bought the GoG version which didn't run properly on my Heroic Games Launcher - Lutris did the job out of the box!
Just dowload the installation files from GoG and run a lutris.net search for the installation routine. Select the installer (64bit worked fine for me) and let it do the magic :-)

GOG version not playable.
Tried some of the fixes from other reports from here but nothing worked. Menu looks broken, no game graphics when blindly clicking to start a new game. Steam version seems to work according to other reports.

Works fine OOTB
Occasionally crashes on startup
Works fine OOTB, however i have had some very rare crashes on startup.

Debian 12 without problems. Debian 11 did not work because of an to old mesa driver.
Debian users should upgrade to Debian 12, where the game runs without any tweaks.
Works perfectly fine
required switch to experimental to or crashes (with Unity progress bar) after pre-title credits
Changed Right and Left bumpers to control camera rotation.
