Dimensional, a first-personal puzzler, is now available for the Oculus Rift / DK2 in Early Access on steam (5 levels + extra experience in credits) or free two level demo.
It uses it's own simple chaperone system and makes you walk, duck, dodge, lean and jump as your progress through deadly chambers. You only need to be able to take a couple of steps towards the camera to play. You'll also be interacting with the world using your droid Digby. Teleporting and FPS-style controls are included.
