Game work out of the box.

Runs good
Slight crackling when switching the window and playing a youtube video on firefox. Could be related to the OS itself. Nothing major though
I didn't have any noticeable issues when playing this game even at 8x in game resolution. I used proton 9.0-2. It supports dualsense, though you have to go through the settings to change the button prompts

Runs flawlessly (not surprising since the game has an official linux version on Itch)

The game will freeze momentarily when opening a menu or on some text boxes if the internal resolution is boosted beyond its 2x initial value (tested 8x and 4x), though it did always resume after a few seconds. Have not tested with any other version of Proton.

The battery gives you a solid 6hrs+ out of the box, but I set it to 4 watts and the GPU to 400 and still ran a solid 60 fps. This probably only granted an extra few minutes or so of battery.
It's basically perfect.
