Only could try it in my standing place (2x3 squares), but still got a little taste of the corridors and the darkness. The fact that you cannot see the floor and the ceiling at the same time really sells the feeling of a dungeon!
PS: would be fun to put swarming rats/snakes on the floor in some rooms to scare ppl :))
PPS: can't wait to try it in a bigger room on the weekend.
PPPS: didn't know VR for Quest was possible in the Godot!
