"I need something to open this."
I played this through to the first crash-to-desktop, at which point I decided I wasn't having fun with it enough to re-do all of it up to that point (about half-wayish or something, according to walkthroughs).
This game has not aged well. The graphics are shoddy and the animations are, well, bad. The dialogue is putrid and very dry, which seems very unlike Doyles' Holmes. The sound of the game is quite good, although the dubbing is dull and lacking of any real... Character.
Most of the game is your standard point and click "find hidden item, use X with Y to do Z and then maybe find something useful". There was a time where I had more patience with that sort of game, but this just seems needlessly complicated. Find all the pieces to be able to find the puzzle, so you can do the puzzle and move on to the next room. Boring. Nothing is really complex or challenging - at least once you've figured out what you actually need to pick up.
Speaking of things to pick up, that's one point I really like.. Some other reviews noted this as a bad thing, but I really love that the items you need don't "stand out" more than any other. That philosophy is brilliant, and, had there been fewer things to pick up, it really helped the game along with regards to immersion.
There's not much else to say about this, really. The game is dull and features way too many "This door is locked" or "I need something to open this" lines. I'm a big fan of Doyle's Holmes, and that Holmes would, quite likely, just have bypassed those locks in some ingenious way - not just looked around for a bit and hope to stumble upon the key.
