I love point-and-click puzzle games and so I am always pn the look out for new ones. This game did not disappoint. It has a great story that is not too complex for a casual player. The puzzles are mostly not too easy, but also not so hard that it makes you frustrated. You don't need to have any prior knowledge, just some apply logic and a bit of abstract thinking. Overall very enjoyable game, which takes about 4.5-5h to finish if you are playing casually.
