They would not know that you need arrow keys to control the tank but if they use a keyboard scheme, they may not even encounter this issue.
Changed left trackpad to arrow keys to change resolution and also control the tank segment since the tank apparently doesn't work with standard controller controls.
The game does not save resolution options and the option it defaults to makes the window too big. You can't change the resolution without keyboard arrow keys.
Cannot change resolution with controller and a tank section can't be controlled with controller (needs keyboard arrow keys to do both).
Some dropped frames here and there

Works fine otherwise but serious issues. Can be bypassed if you use keyboard controls but that's disappointing given the game supports controller.

if you have strange frame issues, reinstall the game, use a more recent GE, finally try upgrading kernel

Works out of the box on latest proton
It's an early access games, there are issues that appear. I could go through the game pretty far.
