Aliens hold a swaying formation, then peel off and dive-bomb your ship\nin classic Galaxian fashion. Pure procedural pixel-art sprites and synthesized\nWebAudio sound — no external image or audio assets.\n\n## How to play\n\n| Input | Action |\n| --- | --- |\n| `←` `→` or `A` `D` | Move ship |\n| `Space` (or `↑` / `W`) | Fire |\n| On-screen buttons | Touch / mobile controls |\n\n- Shoot aliens for points. **Aliens shot while diving are worth double.**\n- Clear all aliens to advance to the next level (dives get faster each level).\n- You start with **3 lives** and earn a bonus life at 5,000 points, then every\n 8,000 after. High score is saved in your browser.\n\n## Scoring\n\n| Alien | Color | Points |\n| --- | --- | --- |\n| Flagship | 🟡 yellow | 60 |\n| Escort | 🔵 cyan | 40 |\n| Grunt | 🔴 red | 20 |\n\n(Double when hit mid-dive.)\n\n## Architecture\n\n```mermaid\nflowchart TD\n H[index.html] --> M[game/main.js
