The manjaro steam cs2d user must force proton hotfix compatibility tool from Steam>Library>Home>CS2D>Properties>Compatibility.

Just use Proton, not native Linux version
Works great with proton

Tries to "load" but crashes instantly
The first frame of the game appearing it instantly disappears on the second frame.
Works just like on Windows

on my pc the game runs only with Proton GE 8-32, i also tried the default one, experimental, 7.0.6 and GE 9.7 without success.
if the game doesn't boot up, try using different versions of proton and proton ge

PROTON_USE_WINED3D=1 PROTON_EAC_RUNTIME=1 PROTON_BATTLEYE_RUNTIME=1 gamemoderun %command% -high -unlockfps -framefixunbounded
At first, the game did not work but after setting up the launch option and selecting the older proton version it worked.
Connect to a random online server
Not working natively but will work with Proton 7.0-4, Proton Experimental or even with GE-Proton7-35
-w 1280 -h 800
1280x800 doesn't appear in video settings, forcing it with launch options works however.

Works out of the box
Little lag in main menu
Played in fast matches and some custom rp servers - all goes pretty smoothly
Works well
Gameplay is normal but I couldn't change the settings because the UI was bugged. other than that I could normally play.
Settings did not work

Able to install, not able to start.
Graphics doesn't matter, it's a 2d game, it should be able to work.
