What it is
Seabright is a coastal city builder made in Unity by GitHub user codersusu. You lay roads, zone residential, commercial and industrial areas, balance jobs with public services, and grow the city until towers and a stadium rise. The creator's notes call it a playable Unity demo built with Codex and GPT-6 Astra: design, programming, art integration, testing and the trailer were handed to Codex and Astra, while the creator set the goals and gave feedback. The game needs no API key to play.
Who it's for: City builders who are also curious how far an AI coding agent can take a game.
