I really enjoyed this game, even if I found it a bit short. The story is engaging and the puzzles varied and challenging. If I have any complaint, it would be to say there wasn't really any clear direction given for a number of the puzzles. I found myself looking to the internet on a couple of occassions when I had no clue what I was supposed to do with a puzzle (and I'm too stubborn to click the "skip" button that pops up when you take too long with one).
The characters were well done, with good voice acting, though it could be jarring to see the lips moving not quite in sync. I also noted how, when presented with a locked door, Watson would say "Locked" in a frustrated tone, while Sherlock would calmly muse, "Closed." There are a lot of lovely details to note and I appreciated the ability to choose my POV. All in all, this is a good puzzle/point & click game,
