The flashlight brings illumination, traversal, and object manipulation into one tool. Collecting key items opens new areas, while encounters with enemies interrupt the search.
Portal Flashlight
The flashlight places alternating blue and red portals. Linking two positions lets the player move across the environment and approach spatial puzzles from a different route.

Object Suction
Switching the flashlight’s bulb enables suction: lock onto a compatible object and pull it closer. Glowing blue particles identify objects that respond to this ability.

Game Design
The original design document connects the narrative, hospital layout, and controller interactions around a gradual increase in uncertainty and pressure.
Narrative & Atmosphere
An amnesic protagonist wakes in an abandoned hospital and searches enclosed rooms for clues and a way out. Limited light conceals what lies ahead, letting environmental details reveal the setting a little at a time.
Exploration gives way to dangerous encounters, changing the pace of the search. After reaching the exit, the protagonist wakes in the starting bed again—a looping ending that leaves the escape unresolved.
Level Design
Teach, then open up. Early rooms introduce portals and suction; the more open lobby asks players to choose routes and solve environmental puzzles. Later areas across the walkway add pursuit pressure.
Unlock, then revisit. Key items gate access to hospital floors and wings while allowing backtracking into earlier areas.
Guide through the environment. Yellow lights and particles suggest the way forward without removing the need to explore.
Interaction Design
The controller groups movement and camera control on the sticks, with portal placement, suction, and interaction assigned to separate inputs. This keeps navigation and flashlight actions available within one control scheme.
