Short, amusing, forgettable
It took me three hours to play through this game (I opted for the 'consult a game guide' rather than 'bang head against wall' option), and I'd almost say this is one of the game's strengths: rather than an endless slog though ever-repeating puzzles the game explores the whole space of point-and-click _and then stops_. This gives you an amusing story with marvellous graphics and varied challenges that holds no tedium. All in all, it's an interesting taster of the story of Marco Polo, and a good way to spend an afternoon if you like this type of game.
