Changelog

Version: 1.0.0
Date: 2026-11-12
  Features:
    - First release.
    - The Planet Designer scenario (New game > Scenarios): design Space Age planets in a window with a live preview
      that's generated by exactly the rules the finished planet uses. A "How it works" guide walks through it.
    - World: land shape, liquid (water, lava, oil, ammonia, slime), up to 12 ground tiles from any planet, cliffs,
      plants, rocks, decorations, resources (frequency, size, richness, near the start) and enemies (biters,
      pentapods or demolishers).
    - Planet: gravity, air pressure, magnetic field, solar power, day length, freezing, lightning storms, the space
      route and its asteroids, its place on the star map, and its look (picked from the ground's colour by default).
      "Same as" buttons copy a vanilla planet's physics, and its resources in one click.
    - Production: the planet's own ores and fluid wells, its own science pack, its own recipes, and its own research
      (the discovery technology, and new technologies with rewards).
    - Hand-made start areas: shape the land around the landing spot in Factorio's own map editor.
    - Checks: what could make a planet hard or impossible to play, each with a button to the section that fixes it.
    - Test play: land on your planet as a character, with its own gravity, pressure, solar power, day and night,
      and enemies.
    - Planet codes: Get code makes a code (like a blueprint string); paste codes into the "Planet codes" startup
      setting to add the planets to any Space Age game.
    - Starting planet: start new Freeplay games on one of your planets instead of Nauvis.
    - Sharing: planet packs (several planets in one code), a share picture with a card about the planet, imports of
      anyone's codes, remixes that credit the original author, and codes that say which other mods they need.
    - Three example planets to play or remix: Emberfall, Mirewood and Rimeholm.
