Two people in the discord have had success running the game on steam deck.
Running the game through steam proton, dotnet installed through protontricks, only issue is terrain being missing, unsurprising given deck is an AMD gpu.
Check out the discord link I sent, we've got people running it on steam deck, there's instructions and people who can help out. I ran it under proton, just had to use protontricks to install dotnet first.
There’s a thread in the discord where a bunch of us have gathered, we’re mostly running the game through proton.

Ok, just found this thread, a few of us have congregated on the discord in a suggestions thread. AMD users are having a lot of issues.
