Reviewers and players generally praise the game's atmosphere and unique central concept, though some find the dream sequences uneven:
The game is structured into six nights, each split into two distinct phases:
: Closing your eyes increases your sleep level but also triggers auditory and visual hallucinations. If your Stress Meter maxes out, you suffer a fatal cardiac arrest.
: You freely roam environments like Pinetree Island or the Revivel laboratory to piece together John's past.
