Mirrorstep: Logic Puzzle

You and Echo, your mirror, move at the same time on two boards. Up and down are copied. Left and
right are swapped. Fill every open square on both boards to solve the puzzle.

The catch: a path that fills your board usually drives Echo into a corner. When Echo's way is
blocked by a rock, the edge or its own path, it waits while you keep going. Use those waits at the
right moments and both boards fill up together.
