Super New to Godot, used Claude Code/gpt-oss-120b locally to help me vibecode a simple platformer game about a grumpy mage who follows you around making fun of you lmao.

A developer has rapidly prototyped a complete Godot platformer game in just two weeks using a novel 'vibecoding' workflow powered by Claude Code and local large language models. The game, created by a developer new to the Godot engine, features a unique grumpy mage NPC that follows the player and delivers snarky commentary based on in-game events.

The technical approach involved experimenting with several local LLMs, including gpt-oss-120b, before settling on Claude Code as the primary development assistant. The developer reported significant performance differences between models, with Claude Code providing the most reliable results for game development tasks. The current implementation uses a hard-coded AI system that gathers contextual game data—player actions, events, and environmental changes—and stores them in a chat history that triggers NPC commentary every 10 seconds.

Looking forward, the developer plans to implement a hybrid AI architecture where the LLM uses tool calls to make dynamic decisions, such as switching equipment, healing characters, or pointing out objects of interest. There's also potential for a 'Wizard of Oz' worldbuilding system where the AI could generate enemies and obstacles in real-time. This project demonstrates how accessible AI tools are lowering barriers to game development, enabling rapid prototyping and creative experimentation even for developers new to specific engines or programming paradigms.
