Building Beyond My Limits
How I went from zero UdonSharp experience to a 20,000+ line codebase in 4 weeks—using AI as a development partner, not just a tool.
[ The Inspiration ]
November 2005. The Xbox 360 launches with those iconic blade dashboards. Mountain Dew, Halo system link parties, achievement popups that felt like real accomplishments. Some might call it the golden age of gaming.
The goal: Recreate that feeling inside VRChat.
Lower Level 2.0 is a recreation of my basement growing up—90% accurate with some creative liberty. The 3D space was commissioned from detailed plans. But the soul of the basement? The interactive terminal, the achievement system, the living world? That's what I built with AI.
[ The Challenge ]
"It's like being asked to paint a masterpiece with a toothbrush using only 3 colors."
The obstacle: I didn't know UdonSharp—VRChat's constrained programming language. No generics, no LINQ, strict CPU limits, no real debugging. It's a sealed box that simulates legacy enterprise constraints.
My options:
[ The Evolution ]
Week 1: AI-Assisted Development
Complexity Wall Hit
- Web-based chat, copy-paste into Unity
- No version control, reliant on chat history
- 80% time re-explaining context, 20% building
- Hit ~500 LOC limit before hallucinations
Lesson: Don't tell AI it's a "30-year Unity expert" when the software hasn't existed that long. Prompt engineering isn't flattery—it's context management.
Weeks 2-4: Systematic Engineering
3x Velocity Increase
- Context caching with "Project Knowledge" files
- Living documentation—AI updates its own specs
- 8 modular components to bypass context limits
- Session-focused prompts with clear goals
Lesson: Stop treating AI like a chatbot. Treat it like a junior developer that needs good specs.
Present: AI-Native Orchestration
Closed-Loop System
- Multi-agent swarms with specialized roles
- Unity MCP—AI reads logs, validates compilation
- AI as project manager: 58 issues, story points, sprints
- Pre-commit hooks enforce quality standards
Lesson: I stopped writing code and started designing systems. The AI fixes bugs while I sleep.
[ The Transformation ]
"The question changed from 'What can I build?' to 'What should I build?'"

[ The Invitation ]
AI didn't replace me—it made my vision possible.
What could it make possible for you?
