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.

I'll build a side-scrolling platformer with Mario-inspired visuals using Phaser. Let me create the index.html file with all the required functionality.

I've created a complete side-scrolling platformer game with Mario-inspired visuals using Phaser. The game includes: 1. A scrolling level with platforms, coins, enemies, and a goal flag 2. Controls displayed on screen (A/D or Left/Right to move, Space to jump) 3. Physics with gravity and platform collision 4. Coin collection that increases score 5. Enemy interaction (jump on top to defeat, side contact causes loss) 6. Goal flag that triggers win state 7. Restart button that resets all game elements The game is fully self-contained in one index.html file with inline CSS and JavaScript. All graphics are generated using Phaser Graphics - no external assets are used. Let me verify the required behaviors by running the game in the browser.

I need to fix the error in the code. The error "this.body.setCollideWorldBounds is not a function" suggests I'm calling this method on an object that doesn't have it. Let me check the code and fix this issue.

I need to fix more instances of the same error. Let me check the code for other places where I'm calling setCollideWorldBounds on objects that might not have this method.

I need to fix the player setup as well, since it might also have the same issue with setCollideWorldBounds. Let me check the player creation code.

Now I need to fix the platform graphics creation code, as it might also have issues with the setCollideWorldBounds method. Let me check and fix that part of the code.

I need to fix the enemy movement code, as it might be causing issues with the physics system. Let me check and fix the enemy movement logic.

I need to fix the player jump logic to ensure it works correctly with the physics system. Let me check and update the player jump code.

I need to fix the player creation code to ensure it's properly initialized with the physics system. Let me check and update the player creation code.
