Thanks for the 'achievement', WGS. It means a lot to me.

I've never seen anyone good at creating puzzles that make me think I cheated it, but only to find out that's the way it is to be solved AND makes sense. Puzzles by others that try this fail because they use glitches, very obscure tricks, or even quirks in the programming to achieve solutions they think are clever but rather it come across as pretentious. Consider that an achievement in puzzle design.
