How to play: Click/tap anywhere on the canvas to spawn bouncing echo balls.
Each ball produces a sound on every bounce — the pitch depends on the ball's position or speed.
Balls bounce in rhythm, creating looping polyrhythmic patterns as they lose energy and settle
into shorter bounces at faster subdivisions. Adjust tempo, gravity, and bounce to shape the groove.
Keyboard: Space = tap ball at center, 1-4 = presets, P = pause, C = clear
