It's a good game -- accuracy is one of my pet peeves and I found it annoying that they had a section for the Grand Canyon and it clearly was not the Grand Canyon -- it was Monument Valley -- which makes me question all of the other locations and their accuracy.
Most of the game is okay -- it is a standard griddler game. But, on certain levels they have positioned the menu and options button on top of the numbers required to solve the puzzle and you have to guess at what the numbers are.
A little more thought needs to be put into the placement of elements.
