Description from the author:

Haunted Mansion is a simple game of creepy sounds and surprizes. Your older children will love it as mine do. The plot is simple..... "It's easy to get IN to the mansion....NOT SO EASY TO GET OUT !!!" You must find two hidden keys to exit the house. However, even if you don't find them, the house is a lot of fun to explore.
