Pretty good
I quite like what is offered here, especially with the three difficulty levels, which allows me to run with my mood at a given time. A couple of reservations though : there is quite a bit of repetition, which I guess is usual; so far, there has between at least one clue error per puzzle; and the big one for me is that errors are marked in almost the same colour, making it difficult to identify why you haven't completed a puzzle successfully. Overall, though, a good value-for-money purchase.
