A kid's design doc, turned into a game in one night
For his birthday, Aiden wanted a beat 'em up of his own: the arcade kind where you keep walking right and punching whoever's in the way. He drew the heroes, the bosses and the story on paper first, and every hero is somebody from his family.
His uncle Lex had already built a version with Claude Code. It worked, but it got old fast. Then he got to try Claude Fable 5.2, handed it the brief before bed, and woke up to a complete game: beat a stage's boss, free the relative locked up there, and they join the roster as your next hero.
How he wrote the prompt, how many tokens it took and how the family kept adding themselves to it afterwards are all in his post. It's worth reading the whole thing.
