The game itself is both enjoyable and challenging. The biggest problem with the game, however, is that it will randomly restart. This is a glitch in the game. It will happen generally somewhere between 30 and 45 percent into it. Playing for an hour can often only get you 1 - 2% further in and when you save and stop, it will sometimes restart rather than resume when you log in again. We were told about 50% of the games have the glitch. If you get one without the glitch, it is a good game.
