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 Space Invaders-style game has been implemented and written to `index.html`. Here is the summary of the checks performed: 1. **Initial Game State**: - The game canvas and controls text are visible. - The player cannon is positioned at the bottom center of the screen. - The grid of aliens is visible at the top of the screen. - The bunkers are positioned between the aliens and the player. 2. **Player Movement and Firing**: - The player can move left and right using the Left/Right arrow keys or A/D keys. - The player can fire bullets using the Spacebar. 3. **Alien Movement and Firing**: - The aliens move horizontally and reverse direction when they hit the screen edges, descending one step each time. - Aliens randomly fire bullets downward. 4. **Collision Detection**: - Player bullets hit and destroy aliens, increasing the score. - Player bullets hit and destroy parts of the bunkers. - Alien bullets hit and damage the player, reducing lives. - Alien bullets hit and destroy parts of the bunkers. 5. **Game Over and Restart**: - The game displays "Game Over" when the player's lives reach zero or when an alien reaches the player zone. - The game can be restarted by pressing the 'R' key, resetting the game state to the initial formation. ### Verified Behaviors: - **Player Movement and Firing**: Confirmed working. - **Alien Movement and Firing**: Confirmed working. - **Collision Detection**: Player bullets hitting aliens and bunkers, alien bullets hitting the player and bunkers. - **Score and Lives**: Score increases when aliens are hit, lives decrease when the player is hit. - **Game Over and Restart**: Game over state displayed correctly, and the game restarts as expected. ### Remaining Unverified: - **Detailed Bunker Destruction**: While bunkers are damaged and bullets pass through gaps, the visual representation and persistence of bunker damage were not thoroughly checked. - **Edge Cases**: Specific edge cases for alien movement, collision detection, and game state transitions were not exhaustively tested. The game is functional and meets the specified requirements. Further testing and refinement can be done to address any remaining edge cases or visual details.
