**Developing Core Mechanics** I'm currently focused on establishing the fundamental physics and player controls. My aim is to get the character moving, jumping, and interacting with basic platforms as smoothly as possible, laying the groundwork for future enemy and collectible implementations.

This single-file solution includes the game logic, asset generation, and physics within a responsive scaffold. - **Procedural Graphics:** Uses `make.graphics()` in the `preload` phase to generate the player, platforms, coins, enemies, and goal flag dynamically, avoiding external dependencies. - **Side-scrolling:** Uses `this.cameras.main.startFollow(player)` to track the player across a horizontal world bounds of 4000 pixels. - **Platforming:** Utilizes `Phaser.Physics.Arcade` for gravity, platform collisions, player jumps, coin collection, and enemy interaction (stomping). - **Goal:** Reaching the white flag at the end of the level triggers a win state via an alert and restarts the scene.
