I bought this game with the discount coupon this weekend and am LOVING it. It is complex, innovative, a genre game ("sort of Steampunk meets Jules Verne), and multiple scenes of activity with a lot to do in each. Everything makes sense, even if what you have to do is not always clear from the get-go.
There are many different types of puzzles available rather than presenting you with the same variation over and over. I was eagerly looking forward to each mini-game or puzzle as I played. I must admit that one puzzle bugged me because it had me trying to drag a token through a long maze without bumping the sides, and it got so annoying (it dumps you all the way back to the beginning again, losing all your progress) that I finally Skipped it. No big deal; the only skunk in the garden.
There are the usual "Bonus" items scattered around, that you simply can ignore if you choose to do so. Good, useful map. The pop-ups are not intrusive. As is common these days, you can dial in the Difficulty level that you want. The graphics are good and clear, with nice movement among background scenery in response to the climate of the scene. I would be surprised to hear anyone complain about this game. I haven't gotten halfway through it yet and already know I definitely will replay this one at a later date!
