October 3 Update: Door Fixes and Desktop Improvements

Fixes and changes

Desktop mode (no VR)

- The game no longer waits on the "checking for VR" screen at startup when no headset is connected.

- Chalk and the blackboard eraser now show hint dots.

- Footsteps are quieter and less frequent, including on stairs.

- A certain anomaly in a classroom is easier to notice without VR.
