Prompt for this run

Build a playable Space Invaders-style game on a canvas using procedural graphics. Use HTML, CSS, and JavaScript as needed. Write it to `index.html` in the current working directory using your file tools. Inline your own CSS and JavaScript. Do not use external assets, CDNs, or network requests. No third-party libraries are provided. Required behavior: - Use Left/Right or A/D to move a cannon along the bottom and Space to fire upward. Display the controls and keep the cannon within the playfield. - Start with a grid of aliens that moves horizontally, reverses and descends at the edges, and fires toward the player. Player shots remove hit aliens and increase score once. - Place destructible bunkers between the cannon and aliens. Hits from either side remove bunker material persistently; shots can subsequently pass through the resulting gaps. - Start with three lives. Enemy shots cost a life with brief protection from repeated damage. Aliens reaching the player zone or zero lives causes Game Over; clearing the aliens shows a win state. - Provide Restart to restore aliens, bunkers, score, lives, and player position. Bound projectile lifetime and fire rate. Verify: Test movement and firing during the opening formation. Check alien motion and inspect a shot hitting a bunker or alien for visible damage or score feedback. Use Restart and check the initial formation, bunkers, lives, and score.

The user wants me to build a Space Invaders-style game in a single self-contained HTML file. Let me create a complete game with:

1. Canvas-based rendering
2. Procedural graphics (no external images)
3. Player cannon that moves left/right with A/D or Left/Right
4. Space to fire
5. Grid of aliens that move horizontally, reverse at edges, and descend
6. Aliens fire back at player
7. Destructible bunkers
8. Lives system (3 lives)
9. Game over and win states
10. Restart functionality
11. Score tracking
12. Projectile lifetime and fire rate limits

Let me write this out as a complete, self-contained index.html file.

I'll build a complete Space Invaders-style game in a single self-contained HTML file. Let me write it out:

Good, I've written the file. Now let me open it in the browser to verify the game works correctly.

Now let me open the browser to verify the game functionality:

The initial display looks correct. I can see:
- Score: 0
- Lives: 3
- The alien formation grid at the top
- Four destructible bunkers
- Player cannon at the bottom
- Controls displayed

Now let me test the game by pressing keys to verify movement and firing:

The game displays correctly with the initial formation. Let me test the movement and firing: <run> {"command": "keyboard.type", "key": "Right"} </run>
