Top-down alien shooter · gpt-5.6-sol

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.

**Creating index.html**

I’m thinking about creating an index.html file. I feel like I need to inspect the directory to see if I should use a library. There might be resources already available that could help streamline the process. I’m curious to see what’s in there and how I can leverage existing tools to make my work easier. Let’s explore that directory together and figure it out!

**Planning game development**

I’m focused on creating a polished game using Phaser. The gameplay will rely on WASD for movement and mouse for aiming and firing. I need overlays for starting and game-over screens, all while ensuring it’s self-contained and responsive. I’ll set the dimensions to 1280x720 and generate textures via Graphics. Physics will be arcade-style, with separate player and turret images. I want to include colliding enemies and bullets, spawning waves and incorporating health and scoring systems with particle effects. Sound will use WebAudio, and I might integrate a UI overlay.**Developing enemy mechanics**

I'm working on the alien textures and enemy groups, focusing on bullet physics and collisions. Enemy movement will be manual with controlled velocities, damaging the player upon close contact, and then getting destroyed. I'm setting up a system where enemies spawn every 380ms and there’s a break of 2 seconds once each wave is cleared. The textures will be generated using Phaser Graphics, and I also need to create background elements like stars. Player movement will be normalized, and I want to implement a HUD for variable updates.

MEASUREMENTS

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.
