I just want to know *what the end result should be*. That is not even slightly clear. I had to read the walkthrough for the door puzzle on easy mode, and *still* was incredibly confused what to click to accomplish that because 90% of the interface is wholly irrelevant. There is just way, way, way too much random noise.
I haven't tried it, but almost feel it may be easier on hard mode because, presumably, more of it is relevant and not just noise.
