About
Oscillator Choir is a calm rhythm puzzle about coaxing a scattered constellation back into one shared breath. Tap each drifting voice on its beat to charge a pulse of light, then draw that light across the night sky to pull voices home — a route that sweeps through several tunes them all at once.
• Each voice's hand sweeps one turn per beat — tap it the moment it reaches the top to charge a clean pulse
• Draw a continuous light route from a charged voice; every drifting voice your line passes is pulled into tune
• Interference bands cross the sky and cut any beam they touch, and the breath leaks while voices drift — so keep drawing, and draw well
5 worlds — First Hum, Detuned Fields, The Long Route, Crossing Voices, One Breath — 100 nights. Three optional tools (Metronome freezes the beat for 8s, Tuning Charge restores a lost charge, Wave Ward silences the interference for 10s) for the stubborn nights. Built with Flutter. No accounts. No cloud saves. Core gameplay is fully offline — internet is only needed for optional ads. Contains optional ads; third-party ad SDKs may collect device identifiers for ad serving (see Privacy Policy).
