About This Game

Stellar Nursery is a story-rich idle game. Relight a dead sun, rebuild nine worlds, and listen to P.O.R.T.I.A., a caretaker AI who has been alone too long.

A free demo is on Steam now (~2 hours, through the first Reignite). The full game is due November 2026.

The system is dark. You are the spark.

Something ended here. The sun is cold, the planets are empty, and the only voice left is P.O.R.T.I.A., an ancient shepherd intelligence who has kept the watch alone for longer than she can bear to say.

Together you will light a star, and rebuild everything that circles it.

Condense nebulae, harvest falling stars, and grow Earth from barren rock to a world of billions. Found a colony on Mars. Send probes into the dark past Neptune.

Every world is drawn live and every one of them answers to how you tend it. Earth's continents green as its population climbs. Neglect a world and you will see that too.

She comments on what you build. She remembers what you lose. She gives up her story one transmission at a time, and sometimes, when she thinks you are not listening, she lets something slip.

Her logs, her puzzles and her secrets are the reward for paying attention.

Active or idle, it respects your time. Leave it running while you work and come back to a report of everything she watched over while you were gone.

58 themes dress every planet, every moon and the sun itself. 34 interface tones repaint the whole console, not just an accent. All of it earned through play. None of it sold.

A playable piano. A harmonograph that draws the real orbital resonances of the worlds you own. A prime spiral. A double pendulum. Sealed ciphers, hidden songs, constellations to chart, and a novella that opens a chapter at a time.

None of it is required. All of it is there.

A solar system to keep, and someone to keep it with.
