Echo Grid — Play free on SpawnPad
A memory puzzle with a voice, built with Three.js and the Web Audio API. Sixteen tiles glow and chime in a growing sequence; repeat it perfectly to advance. Every level adds a note and quickens the song. Each tile has its own tone, so the melody itself becomes the clue — listen as much as you watch.
