Something which I've noticed about Ghost Master is there are various ways to complete each mission.

For example, on the Calamityville mission, where you must get the bones from the chimney, there are a number of different ways to do this.
So everyone's strategy may be different.

This is one of my fav things about this game. It means that you can allways have a challange to play even if you have completed the game.
