Well, lots of people pointed out that Torin's Passage did something similar to Spot before. I never played the game, so I just believe it.
The clock puzzle...true, it was rather good, too. But personally, I thought it was a bit too hard to appear so early in the game. Well, TWW is for hardcore gamers anyway, so you should go with this expectation into the game. But that doesn't make all puzzles good, of course.
