Prompt for this run

Using the pre-provided phaser.min.js (global Phaser), build a playable brick-breaker game with a paddle (arrow keys or mouse), a bouncing ball, and a wall of breakable bricks with a score. Use ONLY procedurally generated graphics via the Phaser Graphics API or generated textures — no external image or audio assets whatsoever.

I'm checking whether the ball launched after the click and confirming the paddle correctly tracks the pointer position, then I'll take another screenshot to verify.

I built the brick-breaker game in `/tmp/job-Usi3ZY/index.html`. It loads the local `phaser.min.js`. I only played a short test, so the later parts of the game haven't been exercised. In the test, one click launched the ball and it broke a brick (score went to 10). It then missed the paddle, which cost a life (3 to 2) and put the ball back on the paddle ready to relaunch. The console showed only Phaser's startup log and some WebGL performance warnings, no errors. I didn't test the keyboard controls, game over, restart, or clearing a whole level. - **Controls:** The paddle follows the mouse, or you can use the left and right arrow keys. Click, Space or the up arrow launches the ball. After a game over, a click or Space restarts. - **Bricks and score:** There are 60 bricks in six colored rows. Each brick is worth 10 points. - **Ball and paddle:** Where the ball hits the paddle sets its bounce angle, and it speeds up slightly on each paddle hit. - **Lives and levels:** You have 3 lives. Clearing the wall rebuilds it at the next level with a faster launch speed. - **Graphics:** All graphics are generated at runtime with the Phaser Graphics API, and there are no image or audio assets.
