CELESTAY is a calm idle building game where you fish for materials and grow your home toward the sky. In a world sunk beneath the sea, you stack pieces of a house and spend quiet days fishing and watching the stars. The higher you build, the more constellations and memories fill your world.

About This Game

  • Leave it be, and dreams and blue skies will grow. — Take your time and nurture a small life that belongs only to you.

  • With the fish and wood you gather from fishing, you can expand your home or send letters to friends far away.

    And sometimes, from the “relics of humanity sunk beneath the city,” you can fondly imagine how people once lived long ago.

  • As your building rises higher, constellations that you could never see before begin to appear in the night sky.

    What could be waiting beyond that sky…? —— Let’s witness the story written in the stars.
