Drop Merge Puzzle Game Builder

Paste this into Claude Code and it builds a finished drop-and-merge puzzle game in one index.html. Circle physics, chain reactions, a 10-tier merge chain, next-piece preview, danger line, saved best score, touch, mouse and keyboard controls. No libraries, no image files, works offline. Change 5 fill-ins to reskin it: gemstones, planets, sea creatures, bakery sweets, or your own idea. I built and tested 4 reskins with zero console errors. Made for Claude Code.
