It would say it doesn't work, but I am not an impostor.

Works flawlessly, and the game is pretty fun.

Works perfectly out of the box! Really fun game, even if it is still a bit rough around the edges.

It works out of the box (proton 4.2). Online and offline tested, no problems, good(ish) performance. Tons of fun.

Works perfectly out of the box. Tested online and offline.

Game runs smooth as butter once it has compiled all shaders (which sadly takes a while in this state it is almost unplayable). Adventure Mode doesn't work due to videos, but Libra of Souls does.

It just works! Poor performance in some crowded or complex areas, flawless otherwise.

Unable to run in DirectX 11 mode. After informing you of this fact on first launch, it will fall back to DirectX 9. It works flawlessly after that, other than the occasional shader compilation stutter

For some reason, it works for me at 0.2 FPS when launched as windowed, which is the default. Setting it to fullscreen makes it run at ~30 FPS (may be my drivers, though).
