## What is Crystal Chorus?

Make light sing.

Crystal Chorus is an optical and musical puzzle where every beam must find its resonance. Rotate mirrors, tune prisms and combine colors to awaken every crystal core.

A CAMPAIGN IN CRESCENDO
• 300 unique stages across 6 acts and 30 sections
• Difficulty rises with every stage, with no two consecutive stages at the same level
• New mechanics introduced gradually: chromatic gates, splitters, portals, fusions, logic sensors and the white spectrum

FIND THE PERFECT PATH
• Solve each board in as few moves as possible
• Compare your result with PAR and earn up to three stars
• Undo, restart and freely revisit unlocked stages

CHOOSE YOUR RESONANCE
Dawn, Nebula or Abyss: three visual atmospheres paired with procedurally composed music.

Crystal Chorus is fully playable offline. Your progress and records are stored only on your device. No account, no ads and no data collection.
