Prompt for this run
Build a playable side-scrolling platformer using the provided Phaser library, with a classic Mario-inspired visual style. 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. Use the provided `phaser.min.js` (global `Phaser`) through a plain local script tag; the runner will inline it into the final artifact. Required behavior: - Provide one completable scrolling level with solid platforms, gaps, collectible coins, patrolling enemies, and a goal flag. - Use Left/Right or A/D to run and Space to jump. Display the controls. Apply gravity and platform collision; prevent repeated mid-air jumping. - Landing on an enemy from above defeats it and bounces the player upward. Side contact or falling into a gap causes a loss state. - Collecting a coin removes it and increases the displayed count once. Reaching the goal flag shows a win state. - Keep the camera following the player within level bounds. Provide Restart that resets coins, enemies, player, and camera. - Generate all graphics using Phaser Graphics or generated textures. Do not load image or audio assets. Verify: Test running and jumping near the starting area. Check landing on a nearby platform and camera following as the player moves. Use Restart and check that the initial player position, visible coins, and camera position return.

The user wants me to build a complete side-scrolling platformer game using Phaser.js, all in a single index.html file. Let me first check what's in the current directory to see the Phaser library file, then build the game. Let me start by checking the directory and then build the complete game.
{"command":"ls -la /tmp/job-qyyLn/"}ls: cannot access '/tmp/job-qyyLn/': No such file or directory Command exited with code 2
thinking
The directory doesn't exist yet. Let me check the current working directory and find the phaser.min.js file.
{"command":"pwd && ls -la"}/tmp/job-qyyvLn total 1168 drwx------ 3 node node 4096 Oct 14 02:34 . drwxrwxrwt 6 root root 4096 Oct 14 02:34 .. drwxr-xr-x 3 node node 4096 Oct 14 02:34 .home -rw-r--r-- 1 node node 1181917 Oct 14 02:34 phaser.min.js
thinking
Good, I can see the `phaser.min.js` file is present. Now let me build the complete platformer game. I need to create a single `index.html` file with: 1. CSS in a `<style>` tag 2. JavaScript in a `<script>` tag that loads Phaser from the local `phaser.min.js` 3. All graphics generated via Phaser Graphics 4. A complete side-scrolling platformer with: - Solid platforms, gaps, collectible coins, patrolling enemies, goal flag - Left/Right or A/D controls, Space to jump - Gravity and platform collision - No repeated mid-air jumping - Landing on enemies defeats them (bounces player) - Side contact or falling into gaps = loss - Coins increase display count - Goal flag = win state - Camera following player - Restart functionality Let me write this comprehensive game.

Good, the file is written. Now let me test it in the browser.

thinking
The game loaded but the canvas is black. Let me check what happened. The console shows a `g.quadraticCurveTo is not a function` error, which suggests a Phaser Graphics issue. Let me look at my code and fix the issues. Let me read the file I wrote to see what's there, and then fix the problems.
