**Developing Game Code** I'm focused on building a self-contained HTML file for the classic Snake game. This will include all necessary CSS for styling and JavaScript for gameplay logic, ready for browser rendering. **Implementing Core Game Mechanics** I'm currently detailing the essential game elements, envisioning the canvas, snake segments, food placement, and the fundamental movement and input handling logic. Collision detection and the eating/growth mechanics are next on my mind. **Structuring Game Elements** My current focus is on defining the foundational structure for the Snake game. I'm outlining the HTML elements, including the canvas and score displays, and considering the core CSS for a dark, neon-themed aesthetic. The JavaScript constants and essential variables are also taking shape. **Optimizing Game Loop** I'm refining the game loop, specifically how I'm managing speed. I'm considering the interplay between `setTimeout` and `requestAnimationFrame` for optimal performance and smooth animation. My next steps involve implementing the core drawing and movement functions. **Integrating Core Logic** I'm deep into drafting the fundamental game functions. My current focus is on the `clearCanvas`, `drawSnake`, `moveSnake`, and `drawFood` routines. I'm also working through the logic for `createFood` to ensure it avoids spawning on the snake itself. **Refining Input Handling** My thoughts are now centered on robust input handling. I'm implementing the `changeDirection` logic, paying close attention to preventing 180-degree turns and addressing the classic rapid key press bug with a `changingDirection` flag per tick to avoid self-collision issues. I'm also laying out the `checkGameOver` conditions. **Addressing Input Edge Cases** I'm implementing a `changingDirection` flag within the input handling to prevent the snake from reversing into itself during rapid key presses. Additionally, I'm exploring visual enhancements like segment spacing, a canvas drop shadow, and a "Start Game" overlay for a better user experience. Here is the complete code for a classic Snake game. It includes HTML, CSS, and JavaScript in a single file, featuring score tracking, high-score saving, a sleek retro-modern design, and both keyboard and on-screen controls. ```html Classic Snake Game
