I've been in game dev for over 20 years and just tried vibecoding a production-quality competitive multiplayer .io game in 30 days. Here's the honest breakdown.

**The project:** [nodecontrol.gg](https://nodecontrol.gg) : a competitive multiplayer territory-control .io game set inside a neural network. Free, browser, no install. Built for Vibe Jam 2026. **The build:** 30 days, solo + Claude. Now live in production: 4-region anycast, mobile support, telemetry, in-game help, FTUE. # Stack * **Client:** Three.js (WebGL), vanilla JS, single HTML entry, all visuals procedural (zero external assets: no models, no textures, no sprite sheets). * **Server:** Node.js + `ws` (WebSocket), authoritative game state, 60Hz tick. * **Audio:** All sound effects are procedurally synthesized via the Web Audio API, down to the boost burnout sweep and the elimination crunches. The BGM itself is external `.ogg` tracks streamed through `HTMLAudioElement`. * **Deploy:** Cloudflare Pages (client, free unlimited bandwidth) + Fly.io 4-region anycast (game server, \~$8/mo). * **AI:** Claude throughout. Roughly 1% Sonnet, 80% Opus 4.6, and 19% Opus 4.7. All of it…
