Overview

Step into the shoes of a security officer on their very first day at a mysterious, architecturally complex building. Your primary duty is to patrol the vast stairwell, investigating reported strange phenomena across its many floors. The core gameplay loop revolves around careful observation and decision-making: if all seems normal, ascend; if you detect an anomaly, descend swiftly. Missing too many anomalies can lead to dire consequences.

Inspired by anomaly loop games like The Exit 8, The Stairwell introduces a unique vertical dimension to the genre, offering a sense of immense scale. Players can expect to uncover over 50 distinct anomalies across various difficulty settings, with a clear indicator of remaining discoveries available after completing a game.
