About This Game

You start with one dim star. Click it to make light, spend the light on more stars, and planets begin to form in orbit. Each one gets a name and its own people. They start as a small tribe and work their way up through seven eras, researching technology and building things like a Great Library and a Dyson Swarm.

When progress slows, let your star swell and swallow its inner planets, or go supernova and start again stronger. Along the way you unlock constellations, a spirit tree, divine powers, a nursery where you breed baby stars, and derelict alien ships that hold the pieces of a lost alphabet. Finish the alphabet and things get stranger.

Comets, meteor showers, solar storms and a leviathan drifting past. When worlds line up or cross the face of your star, a rite opens for a short time and gives you a boost if you catch it. Shooting stars give surges, and boosts that run at the same time multiply each other.


• A small, resizable window, with always-on-top and borderless modes, or play it fullscreen.
• Desktop mode: just your solar system floating over your wallpaper.
• Offline progress for your light, your research and your nursery.
• Companion tools in their own windows: focus timer, to-do list, notes, music player, clocks, alarms and a calendar.
• Controller support, rebindable keys, Steam Cloud and three save slots.

• English, German, French, Spanish, Italian, Dutch and Japanese.
