How do I solve Room 4. I'm pressing "space" all the time or click with my mose but nothing moves. Is there a trick? Am I doing something wron? I do have to press the right tile to get into the open square, don't I?
Why is the code on the drawer red-green-blue, when the boxes on top show green-red-blue. That's not a real match, is it?`Had to look at the walkthrough for that last clue...
