High above the city stands an abandoned observatory. At its heart once burned the Great Prism — a lens that gathered starlight and painted the night in color. When it shattered, its light scattered into eighty sealed chambers.
You are the last optician. Rebuild each path of light, chamber by chamber, and bring the Great Prism back to life.
Interlude
This is the whole game in one breath: tap a mirror to turn it, feed the light to the sensor. Par is the true minimum — the solver proved it.
Two mirrors stand wrong. Par 2.
Every level is verified by an exhaustive solver — par is always the true minimum, so three stars are always honestly reachable. Mirrors, prisms, filters, splitters, portals, valves, sensors and gates: each chapter teaches a new instrument.
A puzzle that exists only today. Keep the streak alive.
Endless chambers, tight budgets, three lenses, no hints. How deep can one run go?
The same trial for everyone, all week. Compare your run.
A full offline bright-star and planet finder. Point the back of the phone toward the sky, search named objects, zoom around the horizon — no camera feed, no account. Positions are calculated on-device.
No ads. No tracking. No accounts. Works fully offline. Color marks, haptics, reduced motion, 13 language options — and a board that hums a quiet chord as its lights come true.
Bend the light.
