You are a man whose wife and daughter have disappeared, but you don't know what has happened. Could you be the reason for their disappearance? Or perhaps you are inside a dream? You can't know for sure, but there are three clues within the game that may help you understand what has occurred. Two of them are bad for you and the last one could simply be another skill for a different storyline.
WASD Mover moves the mouse, Space jumps, and Left Ctrl interacts. Q crouches, and there are puzzles or camera interactions.
