The $0.99 game throws you into a randomly generated three dimensional maze (with ladders) and your job is simply to get out as quickly as possible. You are optionally allowed to use a compass and breadcrumbs to mark your way, but these speed up the timer. Your best times required to escape each maze is kept in a high score table.
The developer describes the game as having "fantastic lighting effects, beautiful graphics, and a sublime soundscape combine to create a mysterious atmosphere". And it's true. The atmosphere of the game adds a lot to the overall experience.
