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.

<thinking>The User has asked to build a playable top-down alien shooter using the provided Phaser library. The requirements include player movement, aiming and firing, health, score, wave number, and a game-over state. The game will be written entirely into `index.html` using inline CSS and JavaScript. The game must be self-contained with no external assets or network requests. I need to create the HTML structure, style it, and write the JavaScript to implement the game logic using the Phaser library. I'll start by creating a basic HTML structure and then proceed to style it and implement the game logic.</thinking> <thinking>Now that I've created the basic structure of `index.html`, I need to implement the game logic. I'll start by setting up the player, then implement movement, aiming, and firing. After that, I'll create the aliens and their behavior. I'll also implement the health, score, and wave number display, as well as the game-over state.</thinking> <thinking>I've implemented the player movement, aiming, firing, and basic collision detection. Next, I'll implement the health, score, and wave number display, as well as the game-over state. I'll also implement the logic for generating waves of aliens and increasing their difficulty. Finally, I'll add the procedural graphics generation for the player, aliens, and bullets.</thinking> <thinking>I've implemented the health, score, and wave number display, as well as the game-over state and wave generation. I'll now add procedural graphics generation for the player, aliens, and bullets using Phaser's Graphics or generated textures. I'll also implement the logic for increasing the difficulty of the waves.</thinking> <thinking>I've implemented procedural graphics generation for the player, aliens, and bullets, as well as the logic for increasing the difficulty of the waves. I've tested the movement, aiming, and firing in the opening encounter, and the shots travel toward the pointer, the aliens advance toward the player, and a projectile hit produces visible feedback. I've also checked the initial health, score, and wave. The game appears to be functioning as required.</thinking> <thinking>I've inspected the game and verified that the required behaviors are working as intended. The game is now complete.</thinking> <thinking>I have created the `index.html` file with the requested functionality. I have verified the required behaviors and the game is now complete.</thinking>
