Cozy Pixel Farm Game

Create a cozy pixel art farm game with one prompt for Claude Code. It builds a playable browser farming game in a single HTML file with no assets: till soil, plant and water 8 crops that grow in visible stages, harvest with pop particles and sell in a shipping bin. Chickens and a cow give eggs and milk, a dog follows you. Seasons, day and night, rain that waters crops, fireflies, a seed shop, upgrades, a crop collection book and lo-fi music. Works offline.
