  1. 01

    You write a sentence.

    One prompt is the whole brief. 'Snake but cats, WASD, retro.' The agent fills in what you didn't say — pacing, palette, difficulty curve.

  2. 02

    The agent builds every piece.

    Sprites, tilemaps, audio, the game loop. It spins up a Phaser project, generates every asset, writes the code, iterates on crashes until the build is clean.

    Your game lives at /g/<slug>. Drop it in a chat. Friends play in a tab, no install, no sign-in. Remix theirs, they remix yours.
