**Developing 2048 Game**

I'm focusing on integrating all the necessary HTML, CSS, and JavaScript into a single, self-contained HTML file to create a playable 2048 game experience.

**Generating Game Code**

I'm actively constructing the complete HTML, CSS, and JavaScript for the 2048 game, aiming for a singular, functional file. The core logic, including tile movement, merging, and scoring, is being implemented.

**Constructing Game File**

I'm now focused on assembling all the HTML structure, CSS styling for appearance and animations, and the JavaScript logic to manage game flow, tile manipulation, scoring, and win/loss conditions into a single, self-contained HTML document.

**Implementing Game Logic**

I'm now focused on translating the game rules into JavaScript code, specifically handling tile generation, movement, merging, scoring, and win/lose conditions. This logic is being integrated directly into the existing HTML structure.

**Building Game File**

I am currently focused on integrating all the necessary HTML structure, CSS styling for visual appeal and animations, and the core JavaScript logic to manage the 2048 game's flow, tile manipulations, scoring, and win/loss conditions into a single, self-contained HTML document.

**Developing Game Logic**

I am currently focused on implementing the core JavaScript logic for the 2048 game. This includes handling tile generation, smooth movement animations triggered by arrow keys, tile merging, score updates, and the win/lose conditions, all within a single HTML file.

**Developing Core Game Logic**

I'm currently focusing on the foundational mechanics for the 2048 game. The core objective is to create a functional, single-page web application contained solely within an `index.html` file. This necessitates embedding all CSS within a `<style>` block and all JavaScript within a `<script>` block.

**Implementing Tile Movement**

I'm diving into the core JavaScript for tile sliding and merging. My focus is on creating a robust algorithm that handles movement in all four directions, ensuring tiles shift correctly and merge as expected. This involves careful management of the game board state.

**Structuring Game Layout**

I'm beginning by laying out the fundamental HTML structure for the game. This includes the container for the game board and placeholders for the score and messages, all within a single `index.html`.

**Refining Input Handling**

I'm now focusing on the precise implementation of arrow key event listeners. My goal is to ensure that these inputs trigger the correct movement and merging logic for the tiles on the game board, updating the game state accurately with each valid keystroke.

**Developing Integrated Game Code**

I'm focusing on consolidating all the necessary HTML structure, CSS styling for the 4x4 grid and tiles, and the JavaScript game logic, including tile movement, merging, and scorekeeping, into a single, self-contained `index.html` file.

**Structuring Game Elements**

I'm beginning by laying out the fundamental HTML structure for the game board and score display, preparing to embed all necessary styles and scripts directly within a single `index.html` file.
