Hey benybens, thanks for playing our game! It should have been explained more clearly - your sanity will constantly decrease, the rate of which depending on your proximity to the ghost, along with how fast you're moving (like if you're running, it will decrease faster). That's where the strategy of picking the best options under stress comes in. We had added a subtle sound cue for the ghost so the player had an indication of where it was, but it seems that it needs some tweaking to be more useful as an indicator. We really appreciate the feedback.
