From an idea to a world you can play
Give your AI the guide
It lists every block the engine has, the rules and the mistakes to avoid. Start at llms.txt on this site.
Describe your game
A shooter, a dungeon run, a school lab, a platformer. Your AI writes the whole project as one JSON file.
Import, publish, play
The Create page checks the whole file and lists every problem, with a button that copies the list back to your AI. Then publish and play alone or with friends.
Copy it, change the idea, paste it into your AI
Read the engine guide for AIs at this site: [this site's address]/llms.txt, then [this site's address]/ai/guide.md. Then write ONE JSON project file for this game idea: [describe your game here]. Return only the JSON. Use only blocks from the catalog, and check every field against the schema.
Replace the address with the one in your browser's bar.
Everything in plain text
The rules
The guide explains the engine block by block, with the mistakes the import sees most.
The blocks
Every block, ability and power the engine has, and the exact shape of the project file.
Examples
Small projects your AI can read before it writes yours.
Paste the list back to your AI
The Create page checks the whole file before it creates anything, and lists every problem with where it is. A button copies that list, so you can paste it back to your AI and ask for a fix.
