Paper Physics

Get the ball past the finish. How you solve the page is up to you.

Paper Physics is a hands-on 2D physics puzzle game styled like a premium black-and-white examination paper. Place planks and mechanisms, start the simulation, and keep editing while the ball is already moving.

Build, run, revise

• Lay down planks, pin moving boards into pivots, launch the ball with springs, and erase material to open a route.
• Move, rotate, place, and erase during the simulation to rescue a plan in motion.
• Use Run Again to keep your construction, or Start Over to restore the full level.
• Collect blue stars to choose abilities such as bounce, glide, jump, brake, reverse, or an extra plank.
• Find your own route through sticky hazards, moving parts, and multi-floor layouts.

What's in this demo

The current Windows demo contains all 16 levels of Rolling Start. New tools and mechanics arrive gradually, from simple bridges to pivots, springs, erasing, sticky obstacles, and chained routes. Other chapter names shown in the menu are previews and are not playable in this build.

Controls and language

Mouse and keyboard. Use the on-screen controls or shortcuts to play, pause, undo, redo, rerun, and start over. The game supports English and Simplified Chinese. No Godot installation is required.
