Game Prototype

game-prototype

Unity mini colony-sim-style colony sim vertical slice, built in 7 days using [game-dev-agent](../game-dev-agent/) for asset generation, code scaffolding, balance tuning, and in-game AI Director.

Reference game

콜로니 심 장르. We're building a vertical slice — NOT a clone, NOT competing. Demonstration only.

Scope (locked at start of Day 1)

| Included | Excluded | |---|---| | 2-3 pawns | 10+ pawns | | 3 needs (food, sleep, mood) | 8+ needs | | 2 resources (wood, food) | full economy + production chains | | 3-4 actions (chop, eat, sleep, wander) | building, crafting, research | | 50×50 tilemap | open world / multiple biomes | | AI Director — 3-5 event types | seasons, weather sim, raids | | Utility AI (highest-need priority) | mood / relationship simulation | | Basic save/load (JSON) | autosave / multi-slot / cloud | | Top-down 2D | 3D / isometric |

End-of-day deliverable schedule

| Day | What .exe shows when launched | |---|---| | 1 | Title → Start → empty tilemap + 1 idle pawn, clickable | | 2 | Pawn moves on right-click, needs UI panel ticking down | | 3 | Trees on map, pawn can chop wood, wood counter rises | | 4 | 3 pawns, autonomous needs satisfaction (utility AI) | | 5 | AI Director generates random events (LLM-driven text) | | 6 | Save/load works, BGM + SFX added | | 7 | Polish + demo video + portfolio README |

Each day = builds/day-X-2026-MM-DD.exe snapshot saved.

Build-in-public narrative

Each day's commit log = the agent's contribution that day. Portfolio README at end of Day 7 = "AI agent built this game in 7 days, here's what each day looked like + which agent module did what".

Target audience: AI agent engineer hiring managers at game companies + general tech companies hiring for AI agent / LLM-application roles.
