For me, the clock puzzle was relatively easy.
Instead, I got hung up by the code-breaking puzzle later in the game. I had a hunch about the pattern, but something about the arrangement threw me off. This was the only point in the game I needed to check UHS...
Boy, did I feel silly for missing the obvious.
(Incidentally, I never played the Remastered version, only the original version of The Awakened. Even though I made Holmes run everywhere in first-person view, the way Watson always magically appeared
standing still whenever I quickly stopped and turned around really creeped me out!
) The switching between first- and third-person perspective seemed to work well in SH vs. Jack the Ripper, though.
