I had a couple of issues playing your game, namely that upon start it asked for Spatial Data, (so I restarted to insure my boundary was set up), and then upon loading into the game, I found myself floating above the graveyard, so any physical obstacles didnt seem to affect me. I liked the witch in the corner, I liked the lighting, and running from a crowd always adds to tension as your choices are steadily taken away. If it helps, I started standing (which is my default play position) so maybe that interfered with calibration?
Spooky! Good job!
