I asked Claude to build me an NYC wildlife simulator in one shot. The result is actually pretty fun!

A user tasked Claude with building an NYC wildlife simulator, which Claude completed in about 45 minutes. The user only needed a second session to add mobile controls and fix minor bugs. The user challenged Claude to build a AAA-quality game as a realistic NYC wildlife simulator where players can be a rat, pigeon, or squirrel, using React/Typescript/three.js, without asking any questions.

This report details a user's experience with Claude building a game in a single session, unlike typical iterative development processes.
