As of the 0.8.02 update I can't play in VR. The older 0.75.3 works perfectly fine.
I did also try launching the game while in steam but it just gives a black screen while the game runs on the desktop.

I'm having the exact same issue. I'm trying to run it with an Oculus Rift and it just loads on the desktop. I've tried running it through SteamVR, adding it to my library as a non-Steam game, etc. but nothing has worked thus far. If you found a solution, please let me know! I've been wanting to play this game and it's super frustrating that it's not working.
