Harmonia | HTML5 Pendulum Painter Physics Puzzle Game

Harmonia — Pendulum Painter

Harmonia is a meditative physics puzzle where pendulums become your paintbrush. Turn the dials to set each pendulum’s motion, hit release, and watch ink trace a delicate pattern across the paper. Match the target design as closely as you can — precision earns you stars, creativity earns you satisfaction.
