There is this minor issue that is probably worth looking into, it happens when quitting:

There are also some polygon flickering issues here and there, and some of the loading transitions result in long black screens. Sorry I prematurely logged this as a whitelist request, there are some bugs here.
Loading transition that really takes a while: The one after the ship lands, after the first boss fight and resulting cutscene / conversations, just before transitioning to the town area.
Nothing extracted yet.
Works fine, as long as you remember to turn on a Steam Controller or Xbox compatible controller prior to launching it. Otherwise, it's pretty much a nightmare to intuit the awful keyboard controls and manage to exit the game.

E: Appears to use D3D11, so it appears to be a good opportunity for me to test DXVK.
