Out of the box, could only dash and attack. Using -PROTON_USE_D9VK lets you move and interact. Basically makes it playable.

After using this flag and having it load, I tried only using -PROTON_NO_D3D11 and it worked, so I ran it with no flags, and it worked. Somehow running it with the D9VK enabled fixed it. Using Proton 4.11-13 when it started working. Proton Experimental worked when going back to it. Looks like running -PROTON_USE_D9VK did the trick

Almost no controls on initial launch, mouse/keyboard or controller. Fixed by -PROTON_USE_D9VK
