It separates design, implementation, and independent review, preserves project decisions across sessions, and turns playtest feedback into follow-up work. Guide development yourself or delegate a bounded goal. Developed with GPT-6 Astra, with a playable Snake demo and development records. Free and MIT-licensed.
