Picked up HL:A last night, been playing it for about an hour now, using my Oculus Quest (The first one, not the 2) and Virtual Desktop. 

I'm very impressed, the graphics are nice and even though my HMD's sharpness is questionable I can still read small in-game writings such as on the backs of books. Very fun so far, a little spooky in places though admittedly I get spooked easily so ymmv. 

Had a little trouble getting to grips with the gravity gloves, like, the object I WANT to grab is what I feel like i'm aiming at but the game highlights something 10ft to the right of it and I have to wave my hand around like i'm casting a fucking spell in order to be pointing at the right thing. Is that just valve saying "Fuck you" because i'm using oculus hardware?
