I've played through a few games now, and overall I think they're really well done, and I enjoy them a lot. I have come across some frustrations with the selection of clues used on some of the puzzles. For example, solving a word/letter puzzle would be less frustrating if the letters/numbers were more clear. I guess you could argue that adds to the level of difficulty, but I hate when I've figured out a puzzle, only to find what I thought was a 6 is actually a g. Anyway, very good overall. Kudos
