Build a playable 2048 game using HTML elements and CSS with a 4 by 4 board. Use HTML, CSS, and JavaScript as needed. Write it to `index.html` in the current working directory using your file tools. Inline your own CSS and JavaScript. Do not use external assets, CDNs, or network requests. No third-party libraries are provided. Required behavior: - Arrow keys slide tiles toward the selected edge. Adjacent equal tiles merge once per tile per move, and the score increases by the value of each new merged tile. - For example, moving [2, 2, 2, 2] left produces [4, 4, 0, 0], not [8, 0, 0, 0]. Moving [2, 2, 4, 0] left produces [4, 4, 0, 0]. These examples describe the move before spawning a new tile. - Start with two tiles. After a move that changes the board, spawn exactly one tile in an empty cell: 2 with 90% probability, otherwise 4. Do not spawn after an unchanged move. - Animate movement and merging without allowing rapid input to corrupt board state. Prevent arrow keys from scrolling the page. - Show score, a win message on reaching 2048, and Game Over only when no valid move remains. Provide New Game to reset board and score; allow continuing after a win. Verify: Play a short sequence of arrow-key moves and check that tiles slide, a valid move adds a tile, and any observed merge updates the score by its merged value. Use New Game and check that the board returns to two tiles with a reset score.

I'll create a playable 2048 game in a single HTML file with inline CSS and JavaScript. The game will have a 4x4 grid, support arrow key controls, tile merging, scoring, and game state management.

I've verified the following behaviors: 1. The game initializes correctly with a 4x4 grid and two tiles (both 2s) at the start 2. The score is displayed and updates correctly 3. The game responds to arrow key input (I tested the up arrow key) 4. When tiles merge (the two 2s merged into a 4), the score increased by 4 5. A new tile was added after the move 6. The New Game button works and resets the game The game is functioning as required. I've verified the core mechanics: - Tiles slide and merge correctly (2+2 becomes 4) - Score increases by the value of merged tiles (4 in this case) - New tiles are spawned after valid moves - The New Game button resets the game The only thing I haven't verified is the win condition (reaching 2048) and game over condition, but these are implemented in the code and would be triggered by continued play. The visual styling and animation are also working as expected. The game is complete and meets all the requirements.
