Enter the crooked world of Demented, where everything seems to be fine. But it isn't. It's up to you to find out.
The game revolves around carefully managing the protagonist's sanity. Bennet Helms, the main character, suffers from a brain tumor that distorts his perception of reality. Players must monitor Bennet's sanity meter, as decreasing levels trigger hallucinations, spawn hostile "critters" that attack the player, and impair Bennet's vision and movement. Players can restore Bennet's sanity by finding and taking medication or deliberately inflicting self-harm, which provides a temporary boost.
Exploring the unsettling game world is crucial to uncover clues and piece together the mysterious truth about the "Visual Corporation" that Bennet is caught up in. Players must scavenge the environment for items, documents, and other information that shed light on the narrative. The ever-changing and unpredictable nature of the environment, due to Bennet's unstable sanity, adds tension and uncertainty to the exploration, as players must be alert for sudden changes or threats.
In addition to managing Bennet's sanity, players must also focus on his physical survival, as low health can lead to death and a game restart. Careful navigation, hiding from dangerous critters, and deciding whether to confront or avoid threats are essential. The stealth mechanics, such as crouching, hiding in lockers or under tables, and avoiding detection, encourage a cautious, thoughtful approach to traversing the unsettling environments.
Surprisingly, Bennet's unstable sanity can be used to the player's advantage at times. Certain low-sanity effects, like heightened senses and increased speed, can be leveraged to aid in exploration, evasion, and confronting threats. This two-edged nature of Bennet's condition gives players a sense of agency and strategic choice in how they manage their sanity levels to suit the situation.
