Ammaar shipped a 'flying Tesla Roadster' game built with Gemini 4 (Argon); 20,000+ people have played it since Friday. Quote-tweeter yshan2u notes it took 2 hours of AI work and about 10 minutes of human tweaks.

The workflow is the real story: he fired off an agent loop in the background before a full workday, and the agent autonomously scraped the Roadster site for style and copy, looked up references like Subway Surfers, and iterated on its own.

A year ago, he notes, a comparable game would have taken a weekend of babysitting code.
