You have entered a place where is taken bay darkness. There is no one to save and you are isolated from the outside, your mission is to get out of the house. You start from the first floor. There are many rooms waiting for you, some of them contain the items which is useful for you, so pick them up and equip them. There are arrows on the top right corner which help you to move. The map can help you situate yourself and to make deplacements. Use your items wisely, they are really helpful. Good luck!
