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.

I need to fix the error "alien.setFillStyle is not a function" and ensure the game renders properly. The issue is that I'm trying to use setFillStyle on a Phaser Graphics object, but I need to create the graphics properly. Let me fix this by properly creating the game objects.

I need to fix the issue with the alien and bullet creation. The problem is that I'm trying to use methods like setFillStyle on objects that don't have those methods. Let me revise the code to properly create the game objects using Phaser's graphics system and ensure physics is properly set up for all objects.

I'll finalize the game by ensuring the essential functionality is working and save the file.
