OVERD0SE - Medical Psychological Horror Visual Novel

★★★★☆ 4.5 / 5  ·  800 player ratings  ·  Medical Psychological Horror Visual Novel
OVERD0SE is a psychological horror visual novel about waking after a car accident in a hospital that already feels familiar, with a doctor whose attention becomes impossible to ignore. — Browser player, free playthrough

OVERD0SE puts you in a hospital room after an accident that should have killed you. A doctor seems to know more than he should, and every conversation moves through medical dread, branching choices, character affinity, and yandere pressure. The current demo has two bad endings; the planned full story spans eleven days with dream sequences, updated CGs, and more dialogue.

What OVERD0SE Feels Like

OVERD0SE is a psychological horror visual novel about waking after a car accident in a hospital that already feels familiar, with a doctor whose attention becomes impossible to ignore. The browser player at the top of this page streams the original build straight into an embedded frame - no download, no install, no signup, no itch.io. Press Play, give the page a second to settle, and start the run.

This is a medical psychological horror visual novel built for short, focused sessions. You can read it once in a sitting, or pace it out over a week - both work. The text is dense in places, the visuals are hand-drawn, and the choices matter more than the chrome around them.

How To Play OVERD0SE

You don't need any special setup. Use your mouse or touchscreen to advance dialogue, pick choices, and interact with the game. The browser player handles the rest. Read carefully, take your time, and let the game ask you the question it actually wants answered.

I

Press Play and let the frame load. No install, no signup, no itch.io.

II

Click or tap to advance. Read each line - the small words carry the weight.

III

When a choice appears, trust your gut - the game remembers what you picked.

IV

Replay with a different instinct. Branching Endings are waiting.

Tips Before You Start

Give the page a clean tab if you can. Close noisy streams, let the iframe take the screen, and read with sound on low if your browser allows it. The game isn't hard to click through, but it's easy to skim past a line that does most of the work. Pay attention to small verbs, to who answers first, to the moment a character goes quiet.

If a polite line makes you flinch, follow that flinch. If a request feels too reasonable, remember it. The best run is usually the one where you let the game catch you being polite when you meant to be honest - and the second run is where it stops feeling like a story and starts feeling like an argument with your own willingness.

“Branching Endings in OVERD0SE, and the tone between routes is what makes you want to see them all. Four stars because one route wraps a hair fast for me, but the rest earns them easily.”
