**Initiating HTML Creation** I'm starting by creating `index.html`. My focus is a feature-rich Snake game, and I'm planning a visually appealing design. I want a modern dark theme with neon accents, particularly emerald green for the snake with a glowing effect. **Defining Game States** I've got the core game states mapped out now: start screen, playing, paused, and game over. I'm thinking of adding instructions and a difficulty selector on the start screen. During gameplay, I'll display the score, high score, and a pause button. I'll need a pause overlay too, and a comprehensive game over screen with stats and a restart option. I'm also planning the grid mechanics and controls next. **Implementing Audio Integration** I'm incredibly excited about synthesizing game-over sounds directly within the JavaScript. I'm focusing on controls now, including on-screen directional buttons for touch and mouse, keyboard listeners with `preventDefault` for arrow keys and spacebar (pause), and a sound toggle. I'm also planning responsive canvas scaling and a clear `index.html` structure with HTML5 boilerplate, styled CSS elements, and a game engine.

I have built a polished, playable Snake game as a self-contained single-page web app in `index.html`. ### Features Included: - **Arcade Visual Design**: Dark neon theme with glowing snake head/body, food particles, and a subtle grid background. - **Controls**: Arrow keys (`↑`, `↓`, `←`, `→`), WASD keys, and on-screen touch buttons for mobile/mouse support. Press **Space** to pause. - **Growing Tail & Scoring**: Eating food grows the snake and increases the score. 20% chance to spawn golden high-value food. Speed scales up progressively. - **Sound Effects**: Built-in retro sound synthesizer using the Web Audio API (no external files required). Sound toggle available in the header. - **States & Persistence**: Start menu, Pause overlay, Game Over screen with restart functionality, and High Score persistence stored in `localStorage`.
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.
RUN
EVALUATION
Only a static start menu is shown; clicking PLAY GAME was never triggered by automated inputs, so gameplay never starts.

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.
