I made a Dark Souls-inspired Three.js game with Sol Ultra using Codex Sites. It's fully playable in the browser. 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.

Fable 5.1 one-shot this Dark Souls meets Diablo game. All code, 222 KB total, zero asset files. Every texture, model and sound effect is generated procedurally. The whole sfx system is 7 KB of Web Audio synthesis. It nailed mechanics I only named in text: stamina, dodge rolls, barbarian skills, and a punishing Souls-style boss. The soul pickups and death animations came out way smoother than I expected. What gets me is how much it infers from a few genre references, with no screenshots or video to go on. Reaching this level used to take dozens of prompts in Sol or Opus 5. Anyone with taste can now make really fun games in the browser.
