This was fun. I got stumped a couple of times, but managed to work it all out. Here's a playthrough for anyone else who is stuck...
Also, Bug Report: when in focus mode, you can "click through" to the background, causing a message to appear as if you clicked on the object in the room. This does not affect gameplay.
Thanks will definitely look into this and fix this in a future release.
I had no problem with the dials clue. Great game.
