I like that this game begins inside a room where you have to go through the first trapped door by means of tools and thinking. Also, I feel that the scary animations (e.g., a ghost, a mouse, and a spider) fit well to a dark and haunted environment.
Some items are difficult to find. Thanks to the walk through comments, I almost miss an important book which has blended so well into the background after I turned the switches. Then, I forgot to check a wooden ball which hid a purple gem.
