I've created a playable side-scrolling platformer in the classic Mario style using only the provided phaser.min.js library. The game features: - Procedurally generated graphics for all elements (player, platforms, enemies, coins, goal flag) - Player controls: left/right movement with arrow keys, jump with space bar - Physics-based platform navigation with gravity and collision detection - Enemies that move back and forth; can be stomped on to defeat them - Coins to collect as you progress - A goal flag at the end of the level The game runs entirely within a single HTML file with inline CSS and JavaScript, using no external resources or network requests. All graphics are created procedurally using Phaser's graphics API. The player can run across scrolling platforms, jump over gaps, stomp enemies, collect coins, and reach the goal flag. When the player reaches the goal, an alert will appear congratulating them. This implementation meets all requirements: it uses only the provided phaser.min.js library, contains no external assets, and is fully self-contained within index.html.
