Top-down alien shooter · gemini-2.5-flash
Using the pre-provided phaser.min.js (global Phaser), build a top-down alien shooter: move with WASD, aim and fire at waves of advancing aliens, with health, score, and increasing difficulty. Use ONLY procedurally generated graphics, no external image or audio assets.

**Developing Core Game Loop** I'm currently focused on establishing the fundamental game loop, integrating player movement and basic alien generation. The aim is to get a playable prototype up and running swiftly. **Structuring HTML Framework** My immediate focus is on establishing the foundational `index.html` structure. This includes setting up the necessary `<style>` and `<script>` tags. I'll then integrate the Phaser game initialization directly within this self-contained file, preparing for subsequent game logic implementation.

The `index.html` file has been created with the basic structure and the Phaser game code. I've implemented: - Basic HTML, CSS for centering the game. - Phaser game setup with a single scene. - Procedural generation of graphics for player (triangle), bullet (circle), and alien (square). - Player movement with WASD and rotation towards the mouse. - Bullet firing from the player towards the mouse. - Alien enemy spawning (randomly from off-screen). - Collision detection between bullets and aliens, and player and aliens. - Score and Health display. - Game Over condition. - Simple wave system with increasing number of enemies and speed. I've fixed some variable name conflicts and ensured `bullet.destroy()` and `alien.destroy()` are called correctly. Also, adjusted player rotation for firing. This should be a good starting point for the game. The user can now open `index.html` in a browser to play the game. I believe this fulfills all the requirements.I have created the `index.html` file containing the single-page web app for the alien shooter game. It includes: * **HTML Structure:** A basic HTML document with a title and a simple CSS style to center the game. * **Phaser Library:** Loads `phaser.min.js` which is assumed to be present in the same directory. * **Game Logic (JavaScript):** * **Phaser Initialization:** Sets up the Phaser game instance with Arcade Physics. * **Procedurally Generated Graphics:** Functions (`createPlayerGraphic`, `createBulletGraphic`, `createAlienGraphic`) to dynamically draw and texture simple shapes for the player (triangle), bullets (circles), and aliens (squares/blobs), eliminating the need for external image assets. * **Player Control:** WASD for movement, mouse for aiming and firing. Player rotates to face the mouse pointer. * **Bullets:** A `Bullet` class manages bullet behavior (speed, lifespan). * **Enemies:** An `Alien` class for the enemies, which spawn randomly off-screen and move towards the player. * **Waves and Difficulty:** Implements a basic wave system where `enemiesPerWave` and `enemySpeed` increase with each new wave. * **Collision Detection:** Handles collisions between bullets and aliens (aliens destroyed, score increases) and player and aliens (player takes damage, alien destroyed). * **HUD:** Displays current score, player health, and wave number. * **Game Over:** Triggers when player health reaches zero, pauses the game, displays a game over message and score, and reloads the page after a delay. * **Self-contained:** No external resources, CDNs, or network requests are made. The game is ready to be played. You can open the `index.html` file directly in a web browser.

Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
