Press play to start right here.

Read Trevor’s narration

Pulsekeeper turns a hospital shift into an adventure. You play MEND zero, a tiny robot. You walk the ward, meet patients, learn what's wrong with them, and then go inside the body to help. I'm building it with Three JS, React, and Next JS, with characters I rigged and animated myself. The hospital ties together the conversations, the tool upgrades, and the rescue missions, and your progress saves in the browser. It's a development build, so start a shift and see how far it's come.

A closer look · With Trevor

Let me show you around.

A small robot, a hospital full of people, and a different kind of rescue. Here is how it comes together.

Chapter 01 / 03

Every rescue starts with a person.

The hospital is the link between patient conversations, supplies, and rescue missions. Your first shift begins by finding Nora.

The starting point

Pulsekeeper turns a hospital shift into an adventure. You guide MEND-0 through the ward, meet patients, learn about their conditions, and head inside the body to help.

What I built

I am building it with Three.js, React, and Next.js, with original rigged characters and animated patient models. The hospital connects patient conversations, tool upgrades, and body-rescue missions. Progress is saved in your browser.

Current state

This is a playable development build. Start a shift here, or visit the Character Club from the main menu to meet MEND-0 and try the rescue simulator. I am still developing the game, so expect it to keep changing.
