Sunkeeper

Sunkeeper is an idle game about looking after a star. Click it to make light, fill the sky with more stars, and grow the worlds around it from tribes into spacefaring civilizations. When progress slows, the star can swell or go supernova and the run starts again stronger. Offline progress covers your light, your research and a nursery of baby stars. Hundreds of in-game achievements (100 of them on Steam), Steam Cloud saves, and fully rebindable shortcuts. Playable in English, German, French, Spanish, Italian, Dutch and Japanese. Planned for Steam on Windows in Q1 2027, with a demo planned for November 2026.
