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.
