From the README

A hands-first WebXR arcade defense game for Meta Quest — and any desktop browser. Seated at a floating altar, you defend a core crystal from storm wisps by **pinch-flinging embers** with real hand physics, drawing runes in the air (line = barrier, circle = nova, zigzag = chain lightning) and closing a fist to bend time. No controllers, no teleporting, no roomscale — the entire game lives inside a two-foot radius.

Built with Three.js + WebXR. Zero assets: every material, shader, sound and texture is procedural, so cold start is instant.
