About this app
Open-source pick, made by AI. Slop Store did not make this game. Starfall is published by e01.ai under the MIT license.
According to its README, it was written by Claude Opus 5 driving a multi-agent workflow from a single prompt, with no design document, asset list or architecture given up front. Ships, hulls, planets and effects are generated at runtime from code. Thirteen ship classes, production, research, resource harvesting and an AI opponent. It is a tribute to Homeworld and is not affiliated with Relic Entertainment.
