Prompt for this run
Build a playable top-down alien shooter using the provided Phaser library. 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. Use the provided `phaser.min.js` (global `Phaser`) through a plain local script tag; the runner will inline it into the final artifact. Required behavior: - Move the player with WASD, aim toward the mouse pointer, and fire with the left mouse button. Display the controls on screen. - Start with a playable arena, a living player, and a first wave of aliens that advance toward the player. Player shots damage aliens; contact with aliens damages the player. - Display health, score, and wave number. Award points for kills. After a wave is cleared, start a harder wave by increasing enemy count or speed. - At zero health, stop gameplay and show a game-over state with Restart. Restart restores health, score, and the first wave. - Generate all graphics procedurally with Phaser Graphics or generated textures. Do not use external image or audio assets. Verify: Test movement, aiming, and firing in the opening encounter. Check that shots travel toward the pointer, aliens advance toward the player, and a projectile hit produces visible feedback. Reload and check the initial health, score, and wave.

The user wants me to build a playable top-down alien shooter using Phaser.js. Let me first check what's in the current directory, then build the game. Key requirements: 1. WASD movement, mouse aiming, left-click firing 2. Display controls on screen 3. Player + aliens that advance toward player 4. Health, score, wave number display 5. Progressive difficulty (harder waves) 6. Game over with restart 7. All procedural graphics (Phaser Graphics) 8. No external assets Let me check the current directory first.

Good, `phaser.min.js` is present. Now let me build the complete game. I need to create a single `index.html` file with inline CSS and JavaScript that: 1. Uses Phaser from the local `phaser.min.js` 2. Has a top-down alien shooter with: - WASD movement - Mouse aiming - Left-click firing - Controls displayed on screen - Player with health - Aliens that advance toward the player - Hit detection (shots damage aliens, contact damages player) - Health, score, wave display - Progressive difficulty - Game over screen with restart - Procedural graphics only Let me build this now.

Now let me test the game in the browser to verify it works correctly.

The console error "Cannot read properties of null (reading 'setVelocity')" indicates that the bullet or projectile object is null when we try to call `setVelocity` on it. This likely means the bullet group isn't being set up correctly, or the bullet creation is failing. Let me examine the current code and fix the issue. The game appears to be rendering (we see a black canvas), but bullets aren't working. Let me fix the code.
The error `Cannot read properties of null (reading 'setVelocity')` indicates the bullet group isn't properly set up. Let me fix the code: {{< read file.path="/tmp/job-C7V3SL/index.html" >}}
