This is a great game to pass some time, beautiful graphics. Puzzles were relatively easy, not too easy to be boring, but not super challenging. The only frustrations were that the cut scenes were very slow, for example, when you finished a challenge, you had to wait and watch a sequence of things like towers expanding or walls building, and those were slow. Not really a problem because still enjoyable. The frustrating thing was at the culmination of the game, there was no end sequence. I actually thought it crashed so I started the last chapter over, only to see the same thing. Just after puzzle, you see a little movement and then you’re back to the main menu. I would suggest to the developers to add a simple and exciting sequence at the end to indicate you have completed the game successfully.
