The 7th Guest/Walkthrough

Objective
The aim of this puzzle is to start from the bottom of the house and move to the top by going from window to window. The directions that you take from each window are determined when you first move from that shaped window to another, i.e. if you start at a rectangular window and move left you can only move left from a rectangular window from then on. There are four different shaped windows which will need to be set to the four different directions, once a window has been set to direction it remains set until the end of the puzzle. Also once a window has been set when you land on that shaped window the computer will automatically follow its own route using the directions you have set. The house is in three levels and you will have to pick a start window on each of the levels.
