Graphic designer builds GTA-style browser game with GPT-6 in 37 minutes

A graphic designer used GPT-6 in ChatGPT to build KlipZi City, an open-world browser game, with the first playable version done in 37 minutes. He kept iterating — taxi jobs, paper runs, car damage, and a time machine reverting the city to 1996 or 1986. His key prompting insight: describe what players can actually DO (jobs, rules, rewards, failure modes) instead of asking for a city, which only yields scenery. Playable online; he's soliciting feedback on confusing parts.
