Build the endless gathering game you saw in ads
A former web designer who had never made a game wrote the story while Codex built Point Nemo, refining it through repeated play-and-feedback rounds.

What they did
The poster, a web designer who had just closed their company, wanted the kind of game seen in mobile ads: gather things, sell them, expand your facilities forever. They had never made a game. They wrote the story, Codex built a version, they played it, then gave feedback for the next round.
How it went
They say the build-play-feedback loop produced a polished game called Point Nemo.
Worth knowing
The human's job was story and play-testing, not coding. Repeated short rounds of play and feedback did the polishing.

Help me build a simple browser game where the player gathers [resource], sells it, and spends the money to expand [facilities] in an endless loop. Here is the story and setting: [your story]. Start with a small playable version, tell me how to run it, and wait for my feedback after I play it. Then improve it one round at a time based on what I say.
