Gregg Biermann将《后窗》切分成十九个垂直列，每个列与下一个略有不同步，从作品的时间中心向外回响，在那里整个画面汇聚在一起。

Anna wakes up in a strange white room. She has 60 seconds to escape; when the timer hits zero she drops dead and reawakens in the same room, joined by a shadowy impression of her previous self. Every 60 seconds this cycle repeats and through each iteration Anna must think ahead and learn from her mistakes to solve a series of puzzles and escape this dystopian maze.
