What You'll Build

Throughout the course, you'll build Dungeons & Agents — a text adventure game that runs in your browser.

╔═══════════════════════════════════════════╗
║            DUNGEONS  &  AGENTS            ║

You stand at the entrance of a dark cave.
A cold wind blows from within.

Each lesson teaches a Claude Code concept, then has you apply it to the game. By lesson 10, you'll have a complete game with rooms, items, combat, and a foundational understanding of Claude Code.
