The first version of \"Starfall Armada\" ran in 3 minutes and 22 seconds, and a playable game with a space background and adjusted difficulty was finished in about 30 minutes. The same task took over five hours with Claude Code a year ago.","why_it_matters":"The jump from five hours to 30 minutes for a working game prototype shows Codex is compressing the iteration cycle for solo developers.","published_at":"2026-05-20T01:01:01.000Z","source_count":1,"sources":["ASCII.jp"],"citations":[{"source":"ASCII.jp","title":"Can AI Alone Make Games?
