@Firepal if you run this in your terminal steam steam://unlockh264/ and you try to run the game again, does it work?
@simifor It... looks like that did it? After running that command, I tested Proton Experimental, 9.0 and 10.0, and the game works well.

Symptoms
The game softlocks after the Three Fields Entertainment logo ends. Further logos do not play, and it never transitions to the main menu. If you unfocus the window, the red mouse intended for the game's map follows the system mouse.
Reproduction
Note
This does not occur with the unofficial GE-Proton.
