Hi,
I've tried to play the game and it generally works, except there is a popping noise.
Turning off the background music makes it less noticeable.
OS: Ubuntu 18.10 x86_64
Kernel: 4.18.0-12-generic
CPU: AMD Ryzen 7 2700X
Device: Radeon RX 580 Series (POLARIS10, DRM 3.26.0, 4.18.0-12-generic, LLVM 7.0.0)
Mesa Version: 18.2.2
Proton version: Beta (3.16-4)
I think there's a regression here with Proton 4.11-2, the game has a fatal error crash a few minutes into running it, I don't even get the chance to launch into a playable area of the game most times.
I played the game successfully with prior versions of Proton, maybe even 4.11-1.
Proton 7.0 has regression where title screen and main menu is corrupted. Proton 6.3 works fine.
Tested with Mesa 21.3.5 and 21.3.7, kernel 5.16.12 but difference is in Proton.
What it looks like (Proton 7.0):

What it should look like (Proton 6.3):

I think I'm seeing a regression here where no input is accepted.
Fedora 36.
5.17.11-300.fc36
mesa-vulkan-drivers-22.0.3-1.fc36
UPDATE: The game works under Proton Experimental.
