Shining Knight is the embodiment of justice and he has a very sharp sword can even cleave
wall. Many bad guys are dead on his sword.

Shining Knight arrives at the maze entrance immediately. He can reach any adjacent empty
square of four directions -- up, down, left, and right in 1 second. Or cleave one adjacent wall in 3
seconds, namely, trun it into empty square. It's the time to save his goddess! Notice: Shining
