Using the pre-provided phaser.min.js (global Phaser), build a playable side-scrolling platformer in the classic Mario style: run and jump across scrolling platforms, stomp enemies, collect coins, and reach a goal flag. Use ONLY procedurally generated graphics, no external image or audio assets.

The user wants me to create a single-page web app with a Mario-style platformer game using Phaser. I need to:

1. Create a self-contained index.html file with:
   - CSS in a <style> tag
   - JS in a <script> tag
   - Use the pre-existing phaser.min.js library
   - No external resources or assets
   - Procedurally generated graphics only

2. Game features needed:
   - Side-scrolling platformer
   - Run and jump mechanics
   - Scrolling platforms
   - Enemy stomping
   - Coin collection
   - Goal flag to reach

Let me create a complete, playable platformer game with all these features using Phaser's built-in graphics capabilities (no external images needed - I'll use Phaser's Graphics class to draw everything procedurally).

I've created a complete, self-contained Mario-style platformer game in index.html. Let me verify the file exists and summarize what was built.

Done! I've created a complete Mario-style side-scrolling platformer in `/tmp/ws/index.html`. **Features:** - **Player character** - A Mario-style sprite with hat, runs and jumps - **Side-scrolling** - Camera follows the player across a 3200px wide level - **Platforms** - Ground with gaps, elevated brick platforms, and golden question blocks - **Enemies** - Goomba-style enemies that patrol platforms; stomp on their heads to defeat them - **Coins** - Collectible coins scattered throughout (100 points each, with floating animation) - **Goal flag** - Reach the flag at the end to complete the level (+1000 points) - **Lives system** - 3 lives, lose one by touching enemies from the side or falling in gaps - **Score tracking** - Points for coins (100) and stomps (200) - **Parallax background** - Clouds and bushes scroll at different speeds - **Visual effects** - Coin collection particles, stomp effects, fireworks on level complete **Controls:** - Arrow Keys or WASD to move - Space or Up to jump - R to restart All graphics are procedurally generated using Phaser's Graphics API - no external assets needed!
