Contrary to other mediocre to negative reviews, I think this is a pretty good puzzle game. Yes, the puzzles in World D are still relatively easy for a 22+ year old because they are listed as only medium difficulty. The puzzles do actually get more challenging as the worlds increase and within each world, i.e don’t prejudge the entire world’s difficulty by its first or second puzzle. Additionally, if you’re the type of person to seek out a puzzle-type game involving sequences of numbers, you’re probably the type of person who has the analytical mind necessary to successfully complete these puzzles. So, don’t assume just because you find them easy that an everyday Joe without your mind will. Perhaps you are more special than you think. Also, the techniques (paths) you learn in earlier puzzles (when there are multiple solutions) do help later for the more difficult ones. Therefore, if you’re reading this review, my suggestion would be to consider downloading and playing it. If nothing else, it’s a way to pass the time when waiting for transportation or in your doctor’s office. 🙂
