You noticed a wonderful decoration in this building from outside and so you decided to enter the building to see it from the inside as well. You kept going up from one floor to another until you reached the top floor of the building. One strange thing that you realized after getting to the top is that there was not a single person inside the building. Now you wanted to get down and get out of the building but the elevator is locked. There is no other option but to search each floor and find the keys to escape from all the floors before escaping from the building.
