A cute, mobile-first 3D web puzzle game. Drag & rotate translucent glowing crystal pieces so their glowing line-art fragments align (viewed head-on) into a hidden picture — plus alternate modes: bend a light beam to a target, and assemble small cubelets into a 3D crystal cube. One daily puzzle, escalating difficulty.

Built with React + Vite + TypeScript + React Three Fiber (three.js) + Zustand.

• Ghép hình (align): drag + rotate translucent creatures until fragments form the picture.
• Tia sáng (beam): rotate crystal prisms to route a light beam to the target ring.
• Lắp ghép 3D (assemble): drag color-matched cubelets into a tilted cube's slots.

• Human celebration/consolation lines use the browser's Web Speech API (a real voice).
• Optional real cat recordings: drop files into public/sounds/ (see the README there); a soft synthesized fallback plays when they're absent.
