The demo is live

You can play Stellar Nursery right now, free, on this page.

The demo runs from a dead solar system through the first Reignite, which is somewhere around two hours depending on how much you poke at things. Everything past that point is in the full game, and the demo will show you where it stops rather than pretending it was never there.

What it is: the sun went out a long time ago and the worlds emptied. You relight the star, then go world by world, seeding life onto dead rock and waiting to see if it takes. It runs in real time, so it keeps going while you are away. The AI who runs the station with you was a person before she was an AI, and she remembers it.

There is also a harmonograph, a prime spiral, and a double pendulum in there, none of which you need to finish the game. She built those.

Stellar Nursery is in Steam Next Fest this October and launches in November.

Thanks for wishlisting. Genuinely.

Any click or key skips ahead. · First-time players skip the card and go straight into PORTIA's boot sequence. · Boot lines animate in properly, and skipping the boot fades instead of…Community21 Aug 2026Cosmetic LayersIdle games have a reputation, and we understood it going in. Numbers go up, you close the tab. We built one anyway, because the part we actually wanted to make was the part nobody expects to find.
