This is the fastest path from idea to playable game prototype. It scaffolds a Phaser or Three.js project, implements the core loop (input, movement, scoring, fail state, restart), and gets a dev server running in under two minutes. You get shapes and mechanics, nothing else. No assets, no polish, no deploy. It's explicitly not for production. The smart move here is the subagent pattern: main thread handles infrastructure while a Task agent implements gameplay following strict architectural rules (EventBus for communication, Constants for config, mobile-first input). Use this when you want to validate a mechanic fast, then layer on assets and polish with separate skills. If you need the full pipeline in one shot, use viral-game instead.
