Version 50 is working great, I can confirm that the game is playable under proton and wine tkg 4.3 & 4.4. There are no error messages about sound assets or undetected cpu/gpu. The game it self run at 60fps (my laptop monitor can only handle 60fps) on my potato machine (core i5, Nvidia 730M). And here is the log under wine tkg 4.4.
Good luck and thank you!.
