I want you to help me build a Roblox game from scratch that feels polished and fun right away.

Make it a pet simulator style game with a simple main loop, collecting coins, hatching pets, upgrading stats, and unlocking a few new areas as the player progresses. I also want a basic shop, a rebirth or prestige system, and a clean UI that works well on mobile and desktop. Please set it up so the game is safe, saves player progress properly, and doesn’t feel laggy once there are a lot of pets or effects on screen.

If it helps, use whatever Roblox best practices and current docs you need to get the details right. Start with the core gameplay first, then add the extra systems, then make sure everything is organized and easy to expand later.
