Claude built this for me in one shot (prompt below) in about 45 minutes. I ran a second session only to add mobile controls and fix one or two bugs. There's no AI generated art or assets anywhere, Claude drew it all in code. Built with Three.js. Play it at [blackpaw.games/concretejungle](http://blackpaw.games/concretejungle) Initial prompt: launch subagents on sonnet 5.5 and help me build a triple A quality game that is a realistic NYC wildlife simulator where you can be either a rat, pigeon, or squirrel. Build it with React/Typescript/three.js. Build the game without asking me any questions. Make me proud.
