The game defaults to a native Linux build. It works out of the box but does not support Steam achievements.
Does not support cloud saves
If you want to unlock achievements play Proton version and NOT the native Linux build. Both proton and native builds run well on Deck with no tinkering. I used the default control scheme. Also this game does not support cloud saves. You have to locate and transfer save files manually.

The native version works great out of the box
No cloud save
The game works fine but it's recommended to use proton for the updated version of the game.
- L4 = Right Bumper (Jump)
- L5 = Left Bumper (Crouch)
- R4 = A Button (Interact)
- R5 = F Key (Flashlight)
- Right trackpad sensitivity = 250%
- Right trackpad click = A Button (Interact)
Kona does not support cloud saves. Updating Proton versions may change the directory in which saves are placed and lose existing save files. I suggest manually setting the compatibility to a currently working Proton version and not allowing Steam Deck to auto-select newly releasing Proton versions after you have started a game.
A wonderful experience on Steam Deck with no modification needed. Minor compatibility and control adjustments will make it feel like it was made for the device.
-screen-fullscreen 0
Older version of Unity, needs the "-screen-fullscreen 0" launch option. With that, no issues, no Proton needed.
Performance is pretty terrible at 4K, 20fps
The native didn't work at all for me, but latest Proton works fine (didn't use GE, so maybe I missed a cutscene?)

For me, the native version doesn’t work at all. Proton works but after 5 minutes of gameplay the game bugs (the “car accident” cinematic doesn’t start). With Proton-GE everything works fine, I finished the game without any problem.
