About This Game

Roll, jump, and experiment. Lost Ball is a 2D physics puzzle-platformer where you unlock new abilities throughout the campaign, changing how you move and solve puzzles. Learn what your abilities can do, then combine them with each other and the world around you to solve increasingly complex puzzles.

Make the world work for you

Use lenses to spread or focus laser beams. Use magnets to operate machines. Experiment with fire, fluids, gravity, and destructible terrain as you work out how to overcome each challenge.

Manipulate enemies to activate switches, lift objects, or even carry you.

Build with the editor that built the game

The full level editor used to build the game is yours to use. Build a new puzzle or modify an existing level with the same physics, materials, effects, machines, and gameplay systems used in the campaign.

Connect wires, gears, and gravity fields with snap-on and auto-connect tools. Create custom game modes with scripting, then share your creations through Steam Workshop.

A new campaign and a return to the original

Play a campaign of new puzzles and reimagined levels from the original Lost Ball.

The original Lost Ball won the 2013 Norwegian Game Awards Game of the Year prize.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

Lost Ball's custom physics engine was written from scratch by me, until I used coding agents to speed up development from 2026 and build the game's included level editor, used by me to design all levels in the game. AI is used to generate code, including code to procedurally generate graphics/sound. Estimated total AI prompts: 20,000-25,000.
