I just finished this game. I just want to say outstanding. Before I write this I have to say a few things about other reviews. First off. For those who say the game icon is ugly. Really? Your going to give a low review because of that? Second. Its boring and the music wants to put you to sleep? Give me a break. This is not a FPS. Its not Mario. Its not doom. Its supposed to be a challenging puzzle based game. I do not think that having heavy metal or other types of music would fit into the concept of this game. MAYBE ITS TOO HARD FOR SOME OF YOU. This is a great game and well worth the money. Im sure the developers put a lot of time and effort into this game and to have people rip it because of the icon is ludicrous. This is a beautiful,challenging,and thought provoking game. It really test you mentally. And its very addicting. Hats off to the folks who came up with one of the most original games I have seen on the store in a long long time. Im going to keep playing this for awhile. Its a top 5 game in my library. And it looks great on the iPhone 5 and iPad. Its a must for those who like a challenge. Thank You
