Hello @Draghi, fixme:vulkan:X11DRV_vkCreateWin32SurfaceKHR Application requires child window rendering, which is not implemented yet! in the log points towards https://bugs.winehq.org/show_bug.cgi?id=45277.
Sorry for the late reply, but, yep that definitely seems to be the issue. The game makes extensive use of child-windows
Compatibility Report
System Information

Symptoms
Music plays but the screen is entirely black. Attempting to use a controller/keyboard/mouse doesn't provide any feedback (ie. audio) to indicate that it's performing any actions. Alt-tabbing and returning to the game does not fix the black screen.
However, the game does run under Proton 4.11-13 and apparently at full speed. The only issue I ran into with it was the window flickering (as if the window was being unfullscreen and re-fullscreened) when moving between rooms and the (XFCE) panels ending up on top of the window. It doesn't affect playability however. Running the game directly under a fresh wine install (5.0) also appears to work as well as 4.11-13.
Reproduction
Run the game, it should enter fullscreen and music should start playing, but, the screen will remain black.
