Could you build this?

Partial The front-end mini-game and avatar dress-up UI are straightforward web graphics, but real-time multi-agent co-op interaction and persistent world synchronization with AI residents require complex orchestration.

What it would actually take: The app needs a 2D/3D web canvas engine (Pixi.js, Three.js, or Phaser) paired with real-time multiplayer state synchronization (e.g., PartyKit, Liveblocks, or WebSockets). The core challenge is the AI agent architecture (WebMCP / tool-use orchestration) that allows the AI resident to plan actions, manipulate the shared state, and solve co-op puzzles coherently alongside humans. This requires expertise in agentic frameworks, context memory management, and game state validation.
