More about Faultfinder
Faultfinder is a demo where players diagnose seven machine failures in a pressure ward system. The engineer who maintained it died after the system malfunctioned. Each incident presents three panes: the engineer's annotated code, the machine's live state, and the city's observed outcome. Players use a debugger to step through instructions, set breakpoints, watch registers, rewind, and inject inputs to identify the exact fault and its impact. The demo features machine-verified cases with one correct answer per incident, proven through exhaustive simulation. No programming is required; players read and debug without writing code.
