Hacker News Comment Review
Commenters noted the game detects programmatic clicks via console automation and responds with labeled messages like “Bot” or “Such a smart subject,” confirming behavioral fingerprinting logic is live.
A recurring theme: people tolerate surveillance when it feels aggregated and automated, but react with discomfort when a human reviews their individual session recordings, a split with direct product implications for session-replay tools.
Used in at least one university interface programming course to introduce input events as discrete signals, suggesting pedagogical value for onboarding junior devs to event-driven thinking.
Notable Comments

@Barbing: Dismissing iOS notifications phones home, leaking sleep schedules and app preferences in ways users rarely anticipate.
