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.

Need to build Space Invaders single-file. Requirements. We have 15 minutes. Need to create index.html with canvas, controls, etc. Plan: - Canvas 800x600 or responsive. - Player cannon at bottom. - Aliens grid e.g. 5 rows 11 cols. - Move horizontally, edge check, descend. - Alien firing random. - Bunkers: between. Use pixel-based destructible. Approach: bunker as offscreen canvas or array of blocks. Simpler: each bunker is a grid of small cells (e.g., 12x8 blocks). Player/alien bullets check collision with cells. Remove cell persistently. Visual gaps. Shots pass through. We'll implement bunkers as 4 bunkers, each comprised of bitmap pattern. Pattern: classic shape. We'll have BLOCK size 8px? Actually bunker total width ~80, height 60. Divide into 10x8 cells of 8px approx. Create mask where = shape. - Lives 3, invulnerability after hit. - Game over/win. - Projectiles bound lifetime, fire rate. - Provide UI: score, lives, controls display, restart. Need to verify with browser. Create file.

The image shows initial state looks good. Need verification per addendum: Run application in browser and inspect initial output and console, do brief pass through representative checks, fix clear problems. We should test movement and firing, alien motion, shot hitting bunker/alien, restart. We already did inspect - shows overlay. Need to test interaction. We can use browser tool to click Play, then type keys. We have browser tool with click, key, type etc. Let's try to simulate.
