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?
Do No Harm for PC starts at €7.38 at Difmark, 53% under the €15.79 of the official store — but that is a shared account, not a key of your own. If you want a key tied to your own account, the cheapest is €12.14 at Kinguin.
That €7.38 already includes the Gocdkeys coupon, so apply it at checkout or the store will show you a higher price.
Supply is thin — 3 offers from 3 stores — and thin supply keeps prices steady rather than falling.
The cheapest route is a shared account at €7.38 at Difmark: you get into an account that already owns the game, but it never becomes yours. A key for your own Steam account starts at €12.14 at Kinguin, €4.76 more, and that is the sensible option.
All 3 offers are Global, so the code redeems on any account no matter where it was created.
For most people the key at €12.14 at Kinguin is the sensible buy: the game stays on your own account and it is only €4.76 more than the shared account.

This fantastic game is a Lovecraftian doctor simulator with narrative adventure and deductive puzzling elements. Players run a medical practice in the Victorian era while diagnosing and treating the affected patients. I think of this game as unique and strategic.
