23 Days is an atmospheric first-person psychological horror game where each new day becomes an increasingly terrifying trial.

After an unexplained incident, Alex Ryan awakens in his own home and realizes that the familiar world has disappeared. Beyond the windows is a blinding white light, the doors are tightly sealed, and the house itself begins to change.

The only voice from outside belongs to Morgan. He claims to know the way to salvation.

Following Morgan's instructions, Alex finds himself in places where reality no longer obeys familiar laws.

Over the course of 23 days, he must explore ever-changing locations, confront his deepest fears, and endure events that increasingly blur the line between reality and nightmare. But with each passing day, the world grows more distorted, and the familiar reality begins to collapse. Alex must preserve his will as an ancient darkness sinks ever deeper into his mind.

Each new day brings the inevitable ending closer. When the twenty-third day arrives, there will be no way back.
