This game has a reasonably interesting storyline, clear hidden object screens, fairly logical problems to solve, and some good puzzles. The voice acting, what there is, is quite acceptable, and the graphics are pretty good too. And it does have walkthroughs for each chapter included, as well as extra content including screensaver, music, art and so on. But there are a number of negative things to note. First of all, it can't be loaded onto your pc and must always be played from the disc, which as another reviewer notes does cause some lag and jerkiness in play. Second, it's not really that challenging. The hardest thing I found in it was a chess problem in the bonus mini-games after I had completed the main game, and even that only took a few minutes of thinking. I completed the entire game in less than three hours (which I know because I was awarded an 'achievement' for doing so), without use of hints or walkthroughs. That makes it pretty poor value for money unless you get it for under a fiver. And the achievements aren't that impressive either; most of them are simply for completing chapters of the game. For instance you get an achievement for meeting Alice, which you can't avoid unless you decide not to bother playing the game. On the whole I was underwhelmed; there are better games on the market with much more playing time.
