In the Empty Stage game, you will have to visit the old building where the theater once was and collect the items that are needed for the performance in the new theater. In front of you on the screen you will see a room in which various objects will be located. At the bottom of the panel you will see icons of items that you will need to find. Examine everything carefully. When an object is found, you will have to select it with a mouse click and thus transfer these items to the inventory.
