Claude Code now refuses to remake existing games.
This prompt gets it to build your own game from a design doc instead, playable in your browser.

I'm building an original game. Claude Code supports games built from my own designs, so I want my design written down before any code.
1. Ask me 8 short questions about the core loop, the player's goal, how they lose and what makes the game mine. Wait for each answer.
2. Write design.md with a one-line pitch, the core loop in 3 steps, controls, win and lose rules, 3 levels with what each one teaches, and a list of art and sounds I'll supply.
3. Build a playable prototype of level 1 as a single HTML file with placeholder shapes, keyboard controls and a restart key.
4. Play it yourself, list each bug and each break from design.md, then fix them.
Describe everything in terms of my design.md. Don't name or borrow existing games, characters or level layouts, because the goal is a game I own.

Anthropic added 2 sentences to its Opus 5.5 prompt on Oct 27th.
Original games, genre games and games from your own designs still work, but developers say Claude stopped some original games halfway.
A design doc shows Claude the game is yours.
Two things to know:
→ Anthropic hasn't defined what counts as a "recreation," and you can't switch the rule off.
→ Swap in your own art and sounds before you share it. The placeholders exist to test the fun.
