The game only plays on a window on the monitor. I tried to open it in Steam but not working. Need help.

I downloaded this and ran Launcher.exe or Launcher64.exe(i have HP Mixed Reality Headset) ... But that uses SmartSteamEmu which stops Steam from running SteamVR properly.. It just opens SteamVR then i'm stuck on a Black screen with 3 spheres loading...

Looked amazing until I read that a VR is required.

I like the idea...sad for the fact it's VR only
