Asymmetric by Klemens Strasse is double maze puzzle. (There was once a puzzle app called Double Maze.)
  The object is to get both Men to their respective destinations.

1. The black squares represent death, it sends that Man back to its starting point, but not the other Man.  Sometimes, you just have to let that happen.
2. Moving right or up on the Right Grid, does the opposite to the Left Grid.

Asymmetric is a seriously good maze puzzle app. Worth the money. I'm stuck on level 50 or so.
