A man awakens in a strange room, wearing a mysterious helmet.
Inside the room, he finds a note left behind by someone who was there before him.
It states that this place allows time travel for only one day,
and that the door opens only during a specific one-minute window.
To escape, the player must uncover that exact minute by manipulating time and following clues.
What is this helmet, and why is he trapped here?
Uncover the hidden truth by exploring clues scattered throughout the room.
All mysteries come together in the end, revealing an unexpected twist.
