**Developing Game Foundation** I’m currently focusing on establishing the core HTML structure for the Asteroids game, specifically setting up the `<canvas>` element where all the action will unfold. Concurrently, I'm beginning to lay out the basic CSS within the `<style>` tag to ensure the visual presentation is on track. **Structuring Game Elements** I’m now focusing on the fundamental HTML for the Asteroids game, specifically the `<canvas>` element where the visuals will render. I'm also beginning to add basic CSS within the `<style>` tag to frame the initial presentation. **Building Game Skeleton** I’m now focused on constructing the skeletal `index.html` file. This involves setting up the essential `<canvas>` element and placeholder elements for score and lives, while also preparing the `<style>` and `<script>` tags for future CSS and JavaScript implementation.

**Creating Game Framework** I've now established the fundamental HTML structure, incorporating essential elements like the canvas, score display, and game state screens. All core game logic has been integrated directly within this `index.html` file. **Refining Player Input** I'm now focusing on refining the ship's control responsiveness. I'm experimenting with slight adjustments to the acceleration and rotation mechanics to achieve a more fluid and satisfying feel during gameplay. **Testing Game Logic** My focus has shifted to thoroughly testing all implemented game logic. I've confirmed that procedural asteroid generation, collision detection, ship controls, and all game states function as intended within the self-contained `index.html` file.
The Asteroids game has been created and saved to `index.html`. You can open this file in a web browser to play the game.
