From the README

A fast-paced arcade game of color, rotation, and reflex. Rotate your shield to absorb matching orbs — one wrong move and it's over.

The shield's color changes based on its angle around the core. Each of the four color sectors (pink, gold, cyan, purple) occupies a 90° arc. To absorb an orb, your shield must be facing the correct sector when the orb arrives.

Your best score is saved locally in your browser.

The game automatically switches between mouse and keyboard control depending on your last input.

No server, no install, no build tools required.
