Seems to be working on Proton Hotfix now! I'm not sure if this was because of the game updating or proton updating though (99% sure it's the latter). The devs are trying to help with the game's input compatibility on windows as well, as it's getting wonky there as well, so when they tweak that, the game might break on proton as well :P
The game does not boot with an Intel arc card.

I confirm:
Symptoms
Keyboard cannot control game past title menu. Tested on Both X11 and Wayland. Reports from multiple other Proton users confirm that this is not an isolated issue.
Reproduction
Open game and try to use keyboard controls. You may advance past the title screen with them, but past that they will not work.
