**Building Initial Framework**

I'm focusing on establishing the foundational HTML and CSS for this project. My current thoughts are centered on creating a clean, single-page structure with the necessary canvas element, and I'm considering inline CSS for simplicity at this stage.

**Developing Core Logic**

My focus has shifted to the JavaScript implementation, specifically setting up the game loop using `requestAnimationFrame`. I'm also beginning to outline the raycasting engine, starting with a basic map representation and player position.

**Implementing Core Raycasting**

I'm now focusing on the raycasting engine itself. My thoughts are on iterating through screen columns, casting rays, and using the DDA algorithm to find wall intersections, calculating distances and screen heights for rendering.

**Refining Raycasting Logic**

My current thoughts are focused on the raycasting algorithm's core DDA implementation. I'm iterating through screen columns, casting rays, and calculating precise wall intersections to determine distances and subsequently, the correct wall heights for rendering.
