- **Controls:**
- **WASD:** Move camera (forward, left, back, right)
- **QE:** Rotate camera up/down
- **Mouse:** Orbit camera (click and drag)
- **Arrow Keys:** Direct snake (Up, Down, Left, Right)
- **R:** Reset game
- **Features:**
- 3D snake navigates a space grid.
- Eat alien food (👾) to grow and trigger L-system growth.
- Creatures exchange quine messages (hover to see).
- Avoid walls and self-collision.
Enjoy the 3D Galaxian experience!
