Works well with a few quirks, but not enough to take away from the experience.
Music goes missing when firing repeated weapons sometimes. There's also some loud sfx here and there in the main menu.
Couple shots looked missing. Might mess you up when lining up attacks.
Trying to start in Proton gave me an immediate crash. Thankfully Native works just fine.

Just works
Runs flawlessly in native version
runs out of the box
Out of the box works.
Just run it.
Works flawlessly on Ultra graphics :D
Perfect out of the box
Perfect
Runs perfectly out of the box.
Remote Play Together also works great
Often I couldn't join a game my friends invited me to
Launcher needs to be operated via holding Steam button and the mouse, otherwise a flawless experience (e.g. with the native Linux version)
As the game is unsupported where Valve tested it with Proton, it would default to Proton. Selecting the Steam Linux Runtime has to be done manually.
Launcher doesn't support Deck controls, but with pressing and holding the Steam button the mouse can be used to start the game via the launcher.
Both Proton and Linux version do have the launcher. In both cases via the Steam button the mouse can be used to start the game (if you don't change the default controller layout). Game itself works great with Deck controls.

use touchscreen

You have to use the touchscreen for the initial graphics setting tool which pops up on launching. That's really the only complaint.
Online works flawlessly, aside from needing to bind a button to Enter to utilize chat
Runs perfectly. No tinkering and no issues.
Runs well with default Proton couldn't notice a difference to the native Linux version
Runs natively and perfectly on Linux. Having an absolute blast playing with friends!

Error on launch: "Failed to initialize player": "Failed to initialize graphics. Make sure you have DirectX 11 installed, have up to date drivers for your graphics card and have not disabled 3D acceleration in display settings. InitializeEngineGraphics failed"
