I built a multiplayer .io racer in Godot 4 that runs in the browser (full workflow)

For the last 3 days I’ve been building **GRID-SURF.IO**. Think Paper.io, but with neon drift cars that can ride up walls. You leave a light trail, close loops to claim territory, and if someone crosses your line, you crash. Full disclosure: I’m no coder wizard or even vibecode wizard. I basically "directed" this game while Claude Code wrote all of the code and ran the tests. I made the high-level calls, playtested it to death, and iterated. I thought sharing the actual workflow would be more fun than a standard promo post. **The Tech & Multiplayer** * **The Stack:** Godot 4.7 (WebGL2 so it works on phones) hosted on Railway for $5/mo. * **No Assets:** All the 3D models (Blender), synthwave music, and even the trailer cuts were generated purely through Python scripts. No asset packs, no clicking around. * **Networking:** The client and server share the exact same physics code. The server runs a headless Godot instance and dictates the state, but your browser predicts your car…
