Who is Here? is a psychological horror game where the player is trapped in an abandoned hospital. The protagonist must survive 8 long and terrifying days, exploring corridors, wards, and hidden rooms to uncover the presence of strange anomalies.
Each day, the player must search the entire location and carefully observe the environment. Sometimes the walls seem to breathe, a shadow flashes by the window, or whispers echo from an empty ward. But sometimes… everything looks normal.

At the end of each day, the player must make a choice:
- Green Sphere — if no anomaly was detected that day.
- Red Sphere — if an anomaly was present.

The choice determines the outcome:
- A correct decision advances the player to the next day.
- A wrong decision resets all progress, and the cycle begins from Day 1.
