Build a playable 2048 game with arrow-key tile sliding and merging, smooth animations, a score, and win and lose states.

The user wants me to build a complete 2048 game in a single HTML file. I need to include:
1. HTML structure for the game board
2. CSS for styling and animations
3. JavaScript for game logic including:
   - Arrow key controls
   - Tile sliding and merging
   - Score tracking
   - Win state (reaching 2048)
   - Lose state (no more moves possible)
   - Smooth animations

Let me create a comprehensive, polished 2048 game.

I've created a complete, self-contained 2048 game in a single HTML file. Let me verify the file exists and summarize what was built.

Created `/tmp/ws/index.html` - a fully playable 2048 game with: **Features:** - **Arrow key controls** (also WASD and touch/swipe for mobile) - **Smooth animations** for tile movement, merging, and appearance - **Score tracking** with current score and best score (persisted in localStorage) - **Win state** - Shows "You Win!" when you reach 2048, with option to continue playing - **Lose state** - Shows "Game Over!" when no moves are possible - **Responsive design** - Works on desktop and mobile with on-screen controls - **Visual polish** - Gradient background, color-coded tiles, merge animations, score pop effects **How to play:** 1. Open `index.html` in a browser 2. Use arrow keys to slide all tiles 3. Matching tiles merge (2+2=4, 4+4=8, etc.) 4. Reach 2048 to win!

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.

EVALUATION

4/5 working

Functional 2048 game with tile merging, score/best tracking; arrow keys and WASD both move tiles correctly, mouse input inert as expected.

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.
