PHONE (icon top left to open/close phone) to see which doors are locked and solve puzzles. Solve puzzles using the 3 BUTTONS AT BOTTOM of PHONE.

I only recently realised that you can easily split images into multiple pieces, using free online resources. This opens up a world of 3D possibilities. It would be even better if Scratch allowed you to change height without changing width and vice versa. I used pinetools.com. The paintings are The Scream (Munch), Girl with Pearl Earring (Vermeer) and Composition with Red, Blue and Yellow (Mondrian). Other images (library, fish etc) found on google images.
