Evaluation

Do No Harm launched on March 6, 2025 as a Lovecraftian doctor simulator. Since launch, the developer has been actively expanding the game with substantial content additions. A Major Gameplay Update arrived on June 26, 2025, adding new anomalies, new game modes (Infinity, Do No Harm, and Time Rush modes), and quality-of-life improvements. The developer also announced at that time that a Narrative Update was in the works for roughly 2–3 months out. That Narrative Update arrived on February 14, 2026, bringing expanded lore, new alternate endings, and new anomaly events. A follow-up to that narrative update shipped on March 23, 2026, adding more anomalies tied to player choices and a new patient character. The most recent post (May 4, 2026) delivered an accessibility update. Across 38 total news posts, the developer has maintained consistent engagement — including 3 major content drops, 5 feature patches, and 18 bug fixes — since the game's release. The developer has not announced that content development is complete, nor have they outlined any specific upcoming DLC. Given the sustained cadence of major updates (roughly every 6–9 months), the game appears to be in ongoing post-launch development.

About this 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?
