So I wrote a 73-line directive: research the genre, design it, build it, test it, balance it, polish it. One session, no human in the loop. It was explicitly told not to ask questions or wait for approvals, just make the call, write it down, keep going. Then I left. Two hours and 32 minutes later it was done. 5 sectors with bosses, 10 enemy types, 6 unlockable ships, 33 boons with evolution chains, a meta upgrade tree, an endless mode, and music. Around 8,300 lines of vanilla JS that build to a 172 KB bundle. Full disclosure: I’ve since made exactly two changes to the game. Fixed one bug (a piercing-shot boon phased through asteroids without damaging them) and added click-to-aim, because keyboard-only turning felt rough. Ran on Claude Code, Fable 5 xhigh effort.
