D. is a 2D puzzle and mystery game set in a psychiatric hospital. Players take on the role of Sami, a doctor beginning his first shift, and move between patient rooms to conduct conversations while gradually uncovering hidden details about the facility and its occupants.
Gameplay
The core loop centers on steering conversations with patients. Choices in dialogue open new topics once enough information surfaces, and all details pin to a clipboard for later use. Connecting notes forms conclusions that the game does not state outright. Incorrect connections only indicate how many links fail without revealing which ones. A handheld radio serves as a key tool, with a dial ranging from 530 to 1700. Signals appear at precise frequencies to unlock previously inaccessible rooms. Certain hospital areas require holding breath to avoid harm, and injuries cause bleeding that can lead to death. Four distinct causes of death exist, each logged with a timestamp on the clipboard. No traditional save system operates; instead, the game provides a prescription note for players to record progress manually. Sessions last around six hours in total, delivered through pixel art visuals available in English and Arabic.
Game Modes
D. functions as a single-player experience without separate multiplayer options or distinct game modes. All activity occurs within the hospital setting through the same conversation, exploration, and deduction systems. Progress ties directly to the clipboard mechanics and radio tuning across every playthrough.
Investigation and Deduction
Players gather information by sitting with patients and noting responses on the clipboard. Topics emerge naturally from prior exchanges, allowing deeper questions once connections form. The deduction system rewards precise linking of facts to reach unspoken conclusions about the hospital's secrets. Wrong connections provide limited feedback, encouraging careful review of collected notes. Environmental elements such as locked wards and hidden signals add layers to the investigation without altering the central conversation focus.
Atmosphere and Risks
The hospital environment includes unsafe zones where holding breath buys limited time before harm occurs. Injuries from these areas lead to bleeding and eventual death, with each outcome recorded on the clipboard. The radio introduces tension through precise tuning requirements, as some signals exist only at exact frequencies. Curiosity drives exploration into restricted spaces, yet the primary task remains patient care and note-taking to dismantle the facility's mysteries piece by piece.
Is It Worth Playing?
D. suits players who enjoy deduction-based puzzles and deliberate conversation systems in a contained single-player package. The six-hour length, combined with the clipboard deduction puzzles and manual radio tuning, creates a focused experience centered on observation and logical connections. Those interested in pixel-art mystery titles with environmental hazards and no reliance on traditional saves may find the mechanics engaging. The game records deaths explicitly and supports progress through handwritten notes, which adds a tangible layer to repeated attempts or careful first playthroughs. Availability on PC makes it accessible for those seeking a compact indie puzzle title without additional modes or ongoing updates.
