Imagine that your grandma celebrated her 80th birthday the last weekend. Unfortunately you were abroad at that time, so you couldn't congratulate her on this occasion. But now you devised to surprise your grandma at the weekend. When you arrived to her house, you suddenly noticed that the grass was uncut and the flowers were withered. You got inside the house, but couldn't find your grandma despite of your shoutings. Suddenly the door behind your shut and became locked. In the meantime, a strange laughter came from the storey, as if a ghost had occupied the place. Find hidden objects and solve puzzles to get out of the building. Good luck and have fun!
