How it plays

Move one light. The other answers.

Every drag you make moves the Glow — and the Echo mirrors it, inverted. Your +v is its −v. The whole game is learning that symmetry, then finding the cracks in it.

One move, two lights

Drag the Glow; the Echo answers as its point-inverse. Master the mirror — then learn to break it.

A world made of light

No solid objects — deflectors, currents, rifts, crystals, tints, beating gates and gravity wells are all light bending light.

A journey through light

A hand-tuned climb of chapters, each bending light a new way — plus a fresh puzzle every single day.

The experience

Light, in your hands

Real moments from the game — one thumb, two lights, and a whole world made of light.
