You need Proton 6.3-8 to run it on 7.0-4.
There is no audio in the game, but the video on the game page seems to have it, I tested this game on Windows 10 installing it on an NTFS HDD and there is no audio, it doesn't seem to be a Proton problem.
To make this game run, you need to launch it by Proton 6.3-8 with option launch "PROTON_USE_WINED3D11=1 %command%" (the performance will be horrible playing), close it and now run it with Proton 7.0-4 without the option launch, it it will work at 60fps without problems, only with the audio problem that also doesn't work on Windows 10 on my PC, so it has nothing to do with Proton.
Black screen on boot regardless of proton version.
Possibly the most basic game i've ever played and it doesn't run under proton its hilarious. I've switched proton versions with no progress & the logs don't show any errors so unsure what the issue is.
Doesn't launch.
Starts with a black screen out-of-the-box, attempted editing launch options, game continues to start with black screen and commands such as "PROTON_NO_D3D11=1 %command%" causes game to crash upon starting
