jacalulu shares how a simple prompt to build a petting zoo with his daughter grew, over a week on Gemini, into a 15,969-line 3D open world with multiple biomes. His key tip: occasionally ask your agent to step back, review what's been built, and suggest refactors — pausing between 'can we also add…' requests pays off. The better models get, the more side projects explode in scope.
