Description (written by the developer; not a statement by this register)

You’ve been accepted to the night shift at a hidden, normal post office. Your job is simple: examine mail, look for anomalies, and decide what gets packaged. Keep the post office safe. Follow every protocol. And whatever you do... don’t let the wrong ones through. ⚠️ Contains horror elements such as disturbing visuals, tension, and loud sounds. 🎧 Headphones & max graphics are recommended for full immersion ❗ Better experienced with friends! ❓ Will you survive all your shifts... or be shamefully fired?

Growth

2 measurements spanning 10 days. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 87–89 and does not start at zero.
