A CuriousYY adventure
Little planets. A very big adventure.
Meet silly creatures, find your rocket, and learn to fly an orbit. Travel from Neptune to a delightfully make-believe Sun finale.

The game is in English. A computer or tablet gives the clearest view; rotate a phone to landscape. Use a current browser with WebGL and graphics acceleration. Tap to start sound.
Checkpoints save in this browser on this device, not in an online account. Use Continue adventure when you return. An unfinished flight restarts at its first orbit. Clearing site data, private browsing, or changing device can lose progress.
Real ideas, playful worlds: orbital lessons use simplified gravity and transfer orbits. Walkable gas giants, creatures, and the Sun's sweet ending are fantasy.
