From planning to sound,
made together.

There is no fixed order. Go back to any part at any time and change it.

  • Planning

    Work out the genre, rules and screens through conversation. What you decide is kept as a planning document.

  • Story

    Write the world, characters and dialogue together.

  • Art

    Create character and background images, then pick the ones to use.

  • Dev

    Build scenes and code in your Godot project and run them.

  • Sound

    Create sound effects and music and add them to your game.

Parts hand off their results as files, and you approve what goes in.

As the conversation grows,
so does your game.

Shape your ideas in each part's chat,
and keep building what your game needs, one step at a time.
