🚀 The 30-Hour Odyssey: Building a Rust/WASM Game Engine via Augmented "Vibe Coding"

By Jonathan Moutier / Djodjonx Estimated reading time: 15 minutes The Hook Modern web development is a productivity paradise. With frameworks like Nuxt or SvelteKit , everything feels fluid, intuitive, and serene. But the moment you cross the border into high-performance web gaming, that comfort vanishes. You are abruptly forced to choose: either settle for ease of use at the cost of performance, or dive headfirst into the brutal complexity of shared buffers, memory management, and heap stacks. My challenge? To build a third way: a powerful Rust/WASM engine that handles like a modern web framework. This is the chronological, unfiltered account of a 30-hour technical marathon where every line of code was a direct collaboration with my AIs to give birth to Gwen . 🌩️ Hours 0 to 2: The Negotiation and the AssemblyScript Mirage It all began with a simple chat window and Gemini . I wasn't looking for a script; I was looking for an architectural partner. My vision was clear: a WASM-based web
