You find yourself trapped in a dream. If you capture anomalies in the dream with a camera, you might be able to escape.
The core gameplay loop challenges players to meticulously scan the environment, hunting for subtle changes or unusual elements that deviate from reality. These anomalies range from obvious, blatant alterations to the apartment to incredibly minute, easily missable details. Reviewers praise the diversity of the 81 unique anomalies, as it keeps the experience engaging and surprising throughout the 20-minute to 1.5-hour playtime.
The game offers two distinct modes of play. In Normal Mode, an anomaly will always occur at each time interval, providing a more straightforward experience. However, Nightmare Mode introduces an additional challenge - there are instances where no anomaly occurs at all. This forces players to carefully consider whether an anomaly is truly present or if they simply haven't discovered it yet. Even after finding all 81 anomalies, players can enable an option to disable previously discovered ones, adding further replayability.
The game provides a helpful radio item that can be used to get hints on the location of an anomaly. However, using the radio will reset the player's progress for that time interval, introducing a strategic risk-reward mechanic. Additionally, the game offers accessibility options to adjust the "Head Bob" and "Motion Blur" settings, reducing potential motion sickness for players.
