Creaky Escape

With a group of archaeologists you studied the old house, but you do not notice all the work ended and everyone left with this structure, when you came in the door, you realize that you forgot about and locked inside. Yelling does not make sense, since the companions had to leave pretty far away and not hear nothing. Before you become a challenge to find as much as possible the materials at hand, and using them to solve all the puzzles that prevent you from leaving the estate.
