You weren't kidding about luck and patience. I polluted the air pretty well before this one was in the bag!
I did come here last night looking for clues, but the "ghost" clue really didn't help me. Today, it dawned on me about the solution, when I remembered this from somewhere else. But, it still took me many, many tries to put it into action! What relief it was, when I was successful.
I didn't use the reflector, either; I moved right away in the beginning, and salvaged the goop cube.
Thanks for a very challenging level!
P.S. I've decided I can only handle one of your levels every day or so, because they are so hard! But I still like to work through them!
