It was 10 PM on a Tuesday. I had a vague idea for a cozy adventure game — something about dreams, emotions, and crafting — and absolutely zero expectation that it would become a working prototype by morning.
But it did. And I'm still not sure how.
The Setup: An AI Agent Dream Team
Instead of coding everything myself, I assembled a team of AI agents, each with a specific role:
- PM Agent — broke down features into tasks and prioritized the backlog
- Architect Agent — designed the system architecture and data flow
- Lead Dev Agent — wrote the actual GDScript code in Godot 4
- QA Agent — wrote tests, ran them, caught bugs before I even noticed
Think of it like a tiny game studio... except everyone works at 3 AM without complaining.
The Stack
- Engine: Godot 4 + GDScript
- Methodology: TDD (Test-Driven Development) — yes, for a game
- Tests written: 880. Eight hundred and eighty.
- Time: One night (~8 hours of active development)
What We Built: Somnia ✨
Somnia is a cozy adventure game where you explore dreamscapes, interact with NPCs, and craft items using emotions you collect along the way.
Here's what the prototype includes:
🗡️ Combat System
Turn-based combat with dream creatures. Simple but functional — attack, defend, use items, flee.
🌾 Farming System
Plant seeds, water crops, harvest them over time. Classic cozy game loop.
📜 Quest System
Multi-step quests with objectives, NPC dialogues, and rewards. The quest engine supports branching and prerequisites.
🏪 Shop & Inventory
Buy and sell items, manage your inventory, equip gear.
💬 NPC Dialogue
Conversation trees with NPCs that remember your choices (within the session, at least).
🎭 Emotion Crafting
The signature mechanic — collect emotions from dreams and combine them to craft unique items and abilities. Joy + Curiosity = Explorer's Compass. Fear + Determination = Shadow Shield.
All of this. In one night. With 880 tests backing it up.
The "Wait, This Actually Works?" Moment
Around 4 AM, I ran the full test suite for the first time expecting a massacre of red. Instead:
880 tests passed. 0 failed.
I stared at the screen. Refreshed. Ran it again. Same result.
The TDD approach meant every system was built on a foundation of tests first. The agents didn't just write code — they wrote the tests, then wrote the code to pass them. When something broke, the QA agent caught it immediately and the Lead Dev agent fixed it before moving on.
This is the part that blew my mind: what would normally take a solo dev about 4 weeks of prototyping was compressed into a single night. Not because the agents are magic, but because they don't get tired, don't get distracted, and don't skip writing tests because "I'll add them later."
Lessons Learned
TDD for games is underrated. Everyone says it's overkill. Having 880 tests meant I could refactor fearlessly.
AI agents work best with clear roles. A single "do everything" agent would've been chaos. Specialized roles = focused output.
The bottleneck is design, not code. The agents could write code all night, but I had to decide what Somnia should actually be. The creative vision is still very much a human job.
Prototyping speed is insane. This doesn't replace game development — but for validating ideas? Nothing comes close.
What's Next
Somnia is still a prototype. There's no art (placeholder everything), no sound, and the emotion crafting system needs way more depth. But the bones are solid, and that's what matters at this stage.
I'm planning to:
- Add pixel art and animations
- Build out the dream world map
- Flesh out the emotion crafting tree
- Add save/load
- Eventually release a playable demo
