From the README

You don't move a character — you leave light on.

A novel, endless HTML5 light-painting game. Hold the shutter open and steer glowing lights to burn shimmering trails onto a night sky.

Most "photography games" are about pointing a camera and framing a shot. **AFTERGLOW is different: the light you leave on is the gameplay.** Hold your finger down to open the shutter, and every glowing pen you steer paints a permanent, luminous trail onto a long-exposure night photo. It's a calm, beautiful score-chase that's easy to learn and deep to master — and it teaches you to draw better as you play.
