(re: King’s Quest 6, and illogical puzzles… (mini-spoiler))
I remember getting the invisible ink part because the whole thing with the dwarves was like the story of the old blind men and the elephant, where 5 blind men feel different parts of a elephant and think its 5 different things, one feels the leg and thinks its a tree, for example. King’s Quest 4 wasn’t really that bad compared to KQ7. How in the Lord’s name are you supposed to know using the comb on Valanice will make her cry?
