4 Doors Escape

You are the leader of your group of college friends. You are a social person and so your friends have asked you to find a house in the new city where you all can stay together for a college project that will last for about a month. You go to a big house that you know is available on rent. You enter the house to inspect it before talking to the owner about it. You like the house but when you plan to get out of the house you discover that you are lost in the house. There is no one to help you. Find a way to get out of the house.
