On of the big things about KC is that once you start in a certain direction you cannot change direction until you hit the next section of the grid. Think of the maze as a grid.
That's a great way to view the maze.
See Pac-Man as being able to change direction/reverse anytime on the grid lines, but with KC you need to reach certain points to do so.
I tried to find a visual of the mazes indicating points of where you can/can't change or reverse direction - No dice. Perhaps one of the community's talented graphic artist may be able to furnish something to demonstrate the point further.
