what’s coming on the cartridge

What you’ll do once Planet ships.

Today’s page is the trailer. Here’s what the cartridge actually unlocks.

  • WALK · 01

    Walk around your planet.

    Cross the rivers, climb the hills, follow your moons across the sky — 128×128 pixel-by-pixel exploration of the world you just designed.

  • WEATHER · 02

    Code the weather in plain English.

    Type “lightning storms every Tuesday” and the planet listens. The cartridge ships with a Claude-powered language layer, no syntax to memorize.

  • CREATURES · 03

    Make creatures that live there.

    Sketch a fishfox. AI gives it a walk cycle, a sleep cycle, and a name. Drop it in your forest and watch it find a home.

  • VISIT · 04

    Visit a friend’s planet.

    Their world has rules yours doesn’t. Plant a flag, trade a postcard, or fork one of your own — then send it back, changed.
