Jigsaw's Escape Room 1.0.2

Hi, any further info on this monument. Like what the escape room puzzle is and the use of Sound Library Api  (as images show a play me cassette or is that just a prop.)

Thanks in advance

The escape room is a blue card puzzle. I have used static loot tables to make an obscure item in the room teleport the player out. 

Using SoundLibraryApi and Static Loot Tables I have made the cassette recorder play a jigsaw sound file when interacted with.

These plugins are not required but add to the immersion.
