CROSSTOWN Ships Five Agent-Built Fixes
Matt Shumer says AI agents pushed five new versions of CROSSTOWN, a browser-based open-world Manhattan game, in response to player bug reports. The experiment turns live gameplay feedback into an automated development loop.
// ANALYSIS
CROSSTOWN is a compelling glimpse at software that improves continuously after launch, though “self-improving” describes the workflow—not the model changing its own weights.
- –Players act as distributed QA testers by reporting issues from the live game
- –Agents can patch, test, and deploy fixes without requiring Shumer to make every code change
- –Browser delivery makes rapid iteration and feedback collection unusually frictionless
- –The hard problem shifts from writing code to prioritizing feedback and preventing regressions
- –Developers should watch whether speed compounds into quality or simply produces faster-moving bugs
