Build a playable Snake game on a canvas with arrow-key controls, a growing tail, food, score, and a game-over and restart state.

The user wants a complete Snake game with specific features: - Canvas-based rendering - Arrow key controls - Growing tail - Food that appears - Score tracking - Game over state - Restart functionality I need to create a single self-contained HTML file with embedded CSS and JavaScript. Let me plan the structure: 1. HTML structure with a canvas element 2. CSS styling for the game (canvas, game container, score display) 3. JavaScript game logic: - Game state variables (snake position, direction, food, score, game over, etc.) - Game loop using requestAnimationFrame - Snake movement and collision detection - Food spawning - Score tracking - Game over detection - Restart functionality Key implementation details: - Snake will be represented as an array of coordinates - Direction controlled by arrow keys - Food appears at random positions not occupied by snake - Game over when snake hits wall or itself - Score increases when eating food - Restart button resets the game Let me write the complete index.html file with all these features.
I'll create a complete, self-contained Snake game in a single HTML file with embedded CSS and JavaScript.

The user wants a playable Snake game with specific features: canvas-based, arrow-key controls, growing tail, food, score tracking, game-over state, and restart functionality. I've created a complete, self-contained HTML file with embedded CSS and JavaScript that meets all these requirements. Let me verify the implementation: 1. ✓ Canvas-based game with 400x400 dimensions 2. ✓ Arrow-key controls with prevention of 180-degree turns 3. ✓ Snake grows when eating food (tail is only removed when no food is eaten) 4. ✓ Food spawns at random positions (not on snake) 5. ✓ Score display that updates when eating food 6. ✓ Game-over state when hitting walls or self 7. ✓ Restart functionality via button and space key 8. ✓ Final score display on game over 9. ✓ Increasing difficulty (speed increases every 5 points) The game is fully self-contained with no external dependencies, uses inline CSS and JavaScript as requested, and is ready to play. I should present this to the user and confirm it's working.
I've created a complete, self-contained Snake game in a single HTML file. Here's what it includes: ## Features Implemented: - ✅ **Canvas-based** 400x400 pixel game board - ✅ **Arrow-key controls** (prevents 180-degree turns) - ✅ **Growing tail** - snake grows when eating food - ✅ **Food** - randomly placed, not on snake - ✅ **Score tracking** - updates when eating food - ✅ **Game-over state** - when hitting walls or yourself - ✅ **Restart functionality** - via button or space key - ✅ **Difficulty progression** - game speeds up every 5 points - ✅ **Clean UI** with score display and game-over overlay ## How to Play: 1. Use the **arrow keys** to control the snake 2. Eat the **red food** to grow longer and increase your score 3. Avoid hitting the **walls** or your own **tail** 4. When game over, click "Play Again" or press **space** The game is fully self-contained in `index.html` with no external dependencies - it runs completely sandboxed in your browser with no network requests. You can open the file directly in any modern web browser to play!

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.
