Odd, I found figuring out the polarity the easy part

Excellent puzzle. Once you figure out the polarity of the German Whisper line, it's manageable to solve. Thanks for the puzzle.

Not sure if I concur with VitP'S assessment, but I'd say figuring out polarity and one other step is probably 2 stars, the rest only one. I tend to veer to the harder rating since people looking for a real one star might have a problem.
