The game features: ## Features Implemented: ✅ **Raycasting Engine** - Renders 3D walls using texture mapping ✅ **Procedural Textures** - Brick walls, stone floors/ceilings, and enemy faces ✅ **Player Controls** - WASD for movement and mouse for looking around ✅ **Combat System** - Shoot enemies with spacebar or mouse click ✅ **Game Mechanics** - Health, ammo, scoring, and game over screen ## How to Play: 1. **Movement**: Use WASD keys to move forward, backward, left, and right 2. **Looking**: Move your mouse to look around the maze 3. **Shooting**: Press SPACE or click to fire at enemies 4. **Objective**: Shoot all enemies to earn points and survive! ## Game Elements: - **Maze**: A 16x16 grid with walls and open spaces - **Enemies**: Three enemies placed in the maze with health bars - **Raycasting**: Classic Wolfenstein-style pseudo-3D rendering - **Procedural Textures**: All textures generated programmatically without external assets The game runs entirely in your browser with no external dependencies. Just open the HTML file and start playing! The implementation uses pure JavaScript raycasting for the 3D effect, with all textures generated procedurally using Canvas APIs. The game includes collision detection, shooting mechanics, and a complete user interface.The generated code creates a complete Wolfenstein 3D style maze shooter in a single HTML file with no external assets. The game features: 1. **Raycasting Engine**: Renders 3D walls using texture mapping 2. **Procedural Textures**: Brick walls, stone floors/ceilings, and enemy faces generated entirely in code 3. **Player Controls**: - WASD for movement - Mouse for looking around - Spacebar/click for shooting 4. **Game Mechanics**: - Health and ammo systems - Enemy AI with health bars - Scoring system - Game over screen The implementation is fully self-contained in one HTML file with inline CSS and JavaScript. All textures are procedurally generated using Canvas APIs, satisfying the requirement of no external assets. The game runs in any modern browser and provides a classic first-person shooter experience reminiscent of Wolfenstein 3D.
