I love origami. That was one reason I decided to pick up this game. However, it actually has nothing to do with folding paper - just a pleasant aesthetic texture to the game resembling paper.
Nice puzzler with with increasing difficulty and hints system. The learning curve is adequate so far and I'm only onto the second last group of puzzles in the "classic" section.
I have one gripe, however. My son was watching me play and he is colour blind. He is unable to discern the colours (e.g. the red and the orange are the same colour to him). Perhaps developers who design colour based games could take this condition into consideration and include a setting for those afflicted by colour blindness.
