John Broke His Bones: Ragdoll Physics Platformer

John Broke His Bones is a 2D ragdoll physics platformer where players fling a broken-boned scientist through hazard-filled labs to reach floating med-kits. A lab experiment went wrong, John can’t walk, and the only way forward is to wriggle, flop, and launch his limp body toward the cure.

The setup is simple. The execution is anything but.

How the Game Works

Movement is the whole challenge here. John can’t run or jump like a normal platformer character—he hurls himself forward in clumsy bursts, and every attempt looks slightly different thanks to the ragdoll physics. Players who expect precise controls will need to adjust. The fun comes from learning to work with the chaos instead of against it.

Each lab contains one med-kit. Grab it and John patches up enough to move on. Miss, and you’ll probably watch him crumple into a wall. That happens a lot.

192 Labs and Plenty of Gadgets

The game packs 192 different labs, which is a serious amount of content for a physics platformer. Gadgets keep things from going stale. A rocket gun sends John flying across gaps. Boost boots add speed when wriggling isn’t enough. And the labs themselves fight back with hazards designed to break even more of John’s bones—something the game playfully warns you to avoid.

There’s also a lab editor included. It’s the same tool the developer used to build the official levels, so players can design and test their own labs once they’ve worked through the main set.

Who Made It

John Broke His Bones was created by Harakat. It fits into the tradition of intentionally awkward physics games, where failing is half the entertainment. But the gadget variety and level editor give it more depth than most games in this style. Get the full game with all 192 levels here

As always, remember to have fun!
