Spent some good time this weekend playing "Bending the Light" available on the Oculus Store:-
I know it has been out a couple of years now, but I only spotted it this weekend.
It is a very well put together puzzler where you have to place orbs and mirrors to bend and reflect light beams to a defined target.
Sounds easy, and it is to begin with, but the skill/precision required gets more challenging as you progress.
Highly recommend for a seated fun game in VR.
