Fun, smart humour, nice characters and cool puzzles. Very enjoyable cartoonish game.
Graphics and animation are very well done. You will like the character's personalities, their relationships. Also the dialogues are very pleasant and smart. The story itself was less compelling than the story in Circle of Blood, due to a lesser accent put on suspense and mystery.
Technically, it has nothing more than the first game of the series. So if you should play only one of them, you would better chose Circle of Blood. But if you really enjoyed the first and want more of the same thing, you will not be disappointed with The Smoking Mirror.
