Prompt for this run
Build a playable falling-block Tetris game on a canvas with a 10-column, 20-row visible 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: - Include all seven tetrominoes with legal spawn positions. Use Left/Right to move, Up to rotate clockwise, Down to soft-drop, and Space to hard-drop. Show the controls. - Reject moves and rotations that overlap occupied cells or leave the board. Wall kicks are optional; if unsupported, reject the blocked rotation without changing the piece. - Lock landed pieces, clear complete rows, move rows above downward, and spawn the next piece. Display score, cleared-line count, level, and a next-piece preview. - Award 100, 300, 500, or 800 points for clearing one, two, three, or four rows with one piece, multiplied by the current level. Start at level 1 and increase gravity speed every ten cleared lines. - If a new piece cannot spawn, show Game Over. Provide Pause/Resume and Restart, with restart resetting the board, score, level, and piece sequence state. Hold and ghost pieces are optional. Verify: Move and rotate the first piece, then hard-drop it. Check that it locks into the board, a new piece spawns, and the next-piece preview advances. Pause and resume, then use Restart and check the cleared board, score, and level.

**Creating a polished design** I need to focus on creating something. First, I’ll use writing as a method to express ideas. Then, it’s about designing a polished canvas to give my work a professional touch. I also need to run tests in the browser to see how everything functions together. It's important to make sure it looks great and works well across different platforms. Alright, let’s get started on this!

**Considering key testing methods** I need to get a test key before proceeding with a hard drop. I wonder if using a browser key could be an option here. Should I perform this in parallel, or is a serial approach necessary? My instinct is to start with ArrowLeft and then maybe the up arrow, followed by taking a screenshot or executing a hard drop. It seems like there's a lot to consider here!
