Surprised no one has written a review of this one yet. It's the exact same concept as Raszlo's original concept but made more elegant and cleaner. It's not as intimidating as it looks... as long as you can see the trick.
Too many repeats... The concept is real great but with a smaller scale, it would become enjoyable. As is, I got angry when I landed 4 off and had to restart it. It killed the fun.
