Skull sends you into a dangerous maze where you collect treasure while constantly avoiding deadly enemies. Sinister skulls roam the corridors and mean instant death if touched, while trap doors and holes can suddenly drop you into deeper, much tougher sections of the maze. At first a map helps with navigation, but it slowly disappears, forcing you to rely on memory, caution and a bit of luck. The appeal comes from exploration, memorizing routes and the ever-present risk of a fatal mistake – tense, challenging and heavily focused on awareness and nerve.
