The author describes scaling from a simple game into a system with 20 agents working in parallel on different parts of the game, while they provide continuous notes and feedback. They mention using Gemini 4 R1 for daily 3D modeling, NanoBanana 2.1 for concept art, 3.8 Flash DTS for audio and sound, Lyria for music, and Omni 1.1 for some video work. The finished game is a story-mode, fully playable 3D world with three levels where players guide a manta ray to prevent a disaster by reuniting it with its team, featuring a full attack and gameplay system.
