About the Game

Do No Harm is a doctor simulator with a Lovecraftian twist. You take on the role of a village doctor, diagnosing and treating patients using ancient and often cryptic medical procedures.

If you’re a fan of profession-related simulators or games that test your decision-making under pressure, Do No Harm is a unique blend of strategy and horror that will keep you guessing until the very end.

  • Lovecraftian Atmosphere

    • Nightmarish entities that warp reality as you play, causing hallucinations, blocking your ability to interact with items, and even deceiving you about treatment results.

    • Anomalies creeping into your daily medical practice, impacting your Sanity.

    • Lovecraftian story involving the proxy war between Azathoth and Cthulhu over the island village and through it the world and humanity.

  • 19-th century Doctor Simulator

    • Diagnose patients based on their symptoms

    • Use tools to narrow down treatment possibilities, and inject the patients with the medicine

    • Consult your Book of Medicine—a beautifully crafted grimoire-like guide.

    • Experiment with remedies inspired by Early Modern medicine, and hope they work… or brace for the consequences.

  • Rich Story & Multiple Endings

    • Reputation system impacting how villagers act around you

    • Each diagnosis, treatment, and moral decision impacts the outcome, leading to multiple endings. Find all 12 Endings.

    • Survive 30 Days: Navigate the pressures of treating the sick while also surviving for 30 days in an increasingly hostile environment.

    • Will you save the villagers, descend into madness, or uncover the truth behind the horrors?
