There are perhaps more flaws to this game than it can get away with. However, the areas in which it excels are the most important aspects of a puzzle game such as this, so I'm inclined to give this a thumbs up overall. Bear in mind though, that this game is probably not everyone's cup of tea, depending on how sensitive you are to annoying details and minor flaws.
- The plot is surprising and genuinely intriguing, and keeps you wanting to find out where your next clue leads you.
- The puzzles are sufficiently varied and well-made, and not too easy to solve.
- The atmosphere fits the game and the story perfectly, including some very good voice-work.
- While the plot is great, it also contains quite a few loose ends and logical shortcomings. Some of the deductions of Mr. Holmes are so far-fetched you've got to wonder if he's high.
- Some of the puzzles are overly difficult, and most of them has only rudimentary instructions which are of very little help as to what you're actually supposed to do.
- The gameplay is as linear as it gets, and consequently the game has absolutely zero replay-value.
- Animations and lip-sync are far below par. There is also weirdly little visual difference between gameplay and cinematics, which makes you wonder why they bothered.
- Considering the low-level graphics and effects, the game still manages to take up nearly 10 GB of space.
- Running is only marginally faster than walking, which makes some sections fairly tedious.
