Web Flappy Bird Clone -- 3

I’m creating a browser-based Flappy Bird remake and need a developer who can deliver a smooth, responsive play experience that runs flawlessly in modern desktop and mobile browsers. The core mechanic stays true to the original tap-to-flap concept; however, I want to extend replay value by adding a few key features:

• Multiple levels with progressive difficulty
• A persistent high-score leaderboard saved in local storage or a lightweight back-end (your recommendation welcome)

Please code in vanilla JavaScript, TypeScript with Webpack, or a framework like Phaser 3—whatever you’re most comfortable with, provided the final build remains lightweight and easy to host on a standard web server. All original art and audio assets can be placeholders for now; I’ll swap them out later, so keep the asset pipeline modular.

Deliverables at hand-off:
1. HTML/CSS/JS source (well-commented)
2. Read-me explaining build/run steps
3. Deployed demo link for quick testing

If this scope sounds clear and feasible, let me know your estimated timeline and preferred tech stack so we can get started right away.
