I have officially beaten Nancy Drew: The Silent Spy, after getting horrendously stuck at one point. Here's where I get unstuck.
I had the bad luck to get stuck on one of the puzzles which does not have a hint on the task bar. And...I managed to fail on both parts of the two part puzzle. Here's my rant, in spoiler-vision. Highlight it to read.
Part 1: Nancy's mom says, "Why is a raven like a writing desk? Ask the raven. Follow the raven to the archives." Somehow, this translates to "the word 'raven' is a password on the archive computer". How are you supposed to figure that out on your own? And why hasn't Cathedral changed their archive passwords in the past ten years?
Part 2: I have NO IDEA where the cryptography challenge comes from. The game says that Nancy gets the list of letters, by applying Kate's note (first green, second orange, third red and so on) to the Jabberwocky poem. But I don't see how this is the case. Kate's note only indicates eight letters, maximum, while Nancy's list has over forty letters. Also, Nancy has spaces in her list, and Kate's clue doesn't indicate any spaces whatsoever. Furthermore, why did they even bother giving us the Jabberwocky poem to look at, if Nancy auto-solves the "get the letters from the poem" puzzle? I guess it's just there to look nice, seeing as it's not supposed to be used to get letters from.
I bet things will make more sense to me, when I replay the game.
