I Built a Dungeon Game by Talking to AI

June 20, 2026 · Greg Brainerd

A business team meeting

After building a card game with AI, I went further: a full dungeon-crawler with heroes, stats, armor, essences, and a maze to fight through — Emberfall — built entirely by describing what I wanted and refining it until it played the way I imagined. No code, just conversation.

It’s small enough to run as a single self-contained file, which means it lives right here on this site.

▶ Play Emberfall — runs in your browser, nothing to install.

The interesting part isn’t the game — it’s the method: describe an idea, get a working version in minutes, react to it, and iterate until it’s real. Read the full walkthrough: How I Built a Full Dungeon Game With AI →

Swap “game” for “internal tool,” “customer portal,” or “dashboard,” and that’s exactly how we build software for businesses. Have an idea? Let’s talk.
