phaserjs/phaser ? reverse-engineered prompt

I want a clean starter project for making a 2D browser game with Phaser.

Set it up so it runs nicely on desktop and mobile, works in the browser with good performance, and includes a simple playable demo scene I can open right away. I’d like basic things to already be there, like loading assets, keyboard and touch input, simple movement, a camera, and a few visual effects so it feels like a real game instead of a blank screen.

Please make the project easy to run and easy to edit, with clear instructions for getting started and a sensible folder structure. If you need to check the latest Phaser docs or examples online to make sure you’re using the best current approach, go ahead.
