I made a Dark Souls-inspired Three.js game with Sol Ultra using Codex Sites. It's fully playable in the browser. http://vesperfall.mengto.chatgpt.site I handled the prompts, references, and libraries like img2threejs. The game has shield blocking, dodge rolls, archery, and a full inventory system. Still blows my mind that you can build a 3D game like this in a single afternoon.
