A Reddit user says Opus 5.5 let them build a complete, playable 3D pixel-art game called Willowmere within the limits of a $20 Claude plan, now live to play in the browser.
The game puts you in a small seaside town where you fix a dark lighthouse, restore the Lantern Festival, and along the way farm, fish, decorate your cottage, and befriend townsfolk (and a cat).
