Indie Game Development with AI

The author built two complete 3D games, Inkline Town and Spirit Call, entirely through AI agents without writing or reading any code, using only chat prompts, playtest links, and 3D model previews. He argues that AI moves the hard part of game development from implementation to the choices only a human can make—what game to build, what style, what is fun, and what is broken—and that agents still fail at anything requiring taste, such as detailed anime characters, which forced him to change Spirit Call's art style. He recommends picking a genre around the AI's bottleneck, building verification layers (ECS structure, types, lints, headless tests, recorded playtests, and math models of the economy), and playtesting as a player while reporting what feels off rather than how to fix it.
