ONE BUTTON JAM

One Button. Infinite Creativity.

👋 Welcome!

Welcome to One Button Jam! Can you create an entire game using only one button?

One action. Endless possibilities. Make a platformer, puzzle, horror game, rhythm game, comedy, experiment — anything you want. The only requirement is that the gameplay is built around a single input.

Examples:

• Space
