AIventure: Vibe Coding Journey

Ian Ballantyne, Developer Relations Engineer at Google DeepMind, introduces AIventure, an open source retro dungeon crawler that doubles as a Gen AI masterclass for developers. Built on Angular and Phaser.js and powered by Gemma 4 open weights, the game teaches vibe coding and agentic behaviors through gameplay. What's covered: Prompting a Chicken NPC to vibe code a web app that Gemma 4 writes in HTML, CSS, and JavaScript and renders in an iframe, prompting a Robot NPC that triggers an autonomous thinking loop with tool calls into the Phaser.js engine, and the model-serving options for Gemma 4: fully local with Transformers.js, Ollama, or LM Studio, or routed to the Gemini API or Google Cloud with a config change.
