My take on REA (morluto/rea) after using it with Claude Code to copy the game 2048:

• ✅ It did what it promises. Claude Code used REA to look inside the real 2048 website and rebuilt the game from what it found.
• 🔍 It went deeper than looks. The site draws on a canvas, so REA pulled out the scripts and Claude read the real rules, like "a new tile is a 2 nine times out of ten".
• 🎮 The copy works. One HTML file, arrow keys, merging, score. I played 40 moves with no errors.
• 🐢 About 7 minutes, and it needs Node 22 or newer. Native apps need Ghidra, IDA or Hopper, which I didn't try.
• ⚖️ Use it responsibly. Copying an app's code or design can break its license; a simple game like this is a fair test.
