The task is to build a first-person raycasting maze shooter in the Wolfenstein 3D style. It must be a single-page web app in one self-contained index.html file with CSS in <style> and JS in <script>. ...The task is to build a first-person raycasting maze shooter in Wolfenstein 3D style, all in one self-contained index.html file with CSS and JS inline. No external assets, procedural textures only.

I need to implement:

- Canvas for rendering

- Raycasting engine

- WASD movement, mouse or 2D arrows for turning

- Textured walls procedurally

- Enemies that can be shot

- Simple shooting

- Grid-based maze

- All in one HTML file

Since it's a coding task, I think the "answer" is the code itself, but the user says "Build", so probably provide the code.

But the system is to report the final answer with confidence.

This seems like a programming problem where the response is the code.

I need to generate the code.

Let me try to write the code.

The task is complete. I've built a self-contained single-page Wolfenstein 3D style raycasting maze shooter in index.html. It includes:

The game has been built as a fully self-contained `index.html` (raycaster, procedural textures, enemies, shooting, minimap, retro CRT HUD, pointer-lock mouse look, WASD + arrows, win/lose states, audio FX). Open it in a browser to play.

TAKE IT TO CODE

A single self-contained HTML file — copy it and open in any browser, or reuse the prompt with your own pi-agent run.

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.
