Early Access is the First Act (1 of 3), full VR Support (we made it for VR) and best of all: the Level Editor. The level editor is also made for VR and is very pleasant to use in the Rift.
We're going to be on GearVR very soon, but this is the Rift version - hope you like it!
I tried this out at Rezzed in London and really enjoyed it, has a real Eye of the Beholder/Knightmare feel to it. I've picked up on Steam Early Access to try out when I'm back from the Scottish highlands later this week and will place a steam review after I've tried it out a bit. I'm surprised you haven't gotten more responses here -- this forum seems a bit dead or at least stacked in favour of really short demo experiences or Vr-ified versions of non-VR games
