Quite an interesting adventure game with some good art. The location design is colourful and vibrant, but still easy on the eye. The character details are pretty high as well, especially Mata's during the dancing routines.
The story is quite intriguing, it shows Mata Hari as a brilliant dancer turned spy against her will -- fortunately, her womanly wiles and quick thinking help her overcome every obstacle. However, once you're a spy "the only way out is death" and so Mata is dragged into even more dangerous missions. Her determination to prevent a war is the only* thing that keeps her going.
Gameplay is a simple point-and-click and goes quite smooth in the beginning. Tasks are easy and dialogues and cutscenes build up a great foundation to the tale of Mata Hari. Further in the tasks become more challenging, requiring some clever thinking and problem solving. Minigames also start to appear after the first mission to spice things up -- these range from a catch-me-not train ride through block-swapping puzzles to decoding encrypted messages. These are also easy to learn and simple to solve at first, but get more demanding as the game goes on.
The dancing minigame deserves a special mention, it's what makes the game stand out. Mata Hari is a great dancer, and it is also up to the player to take care of this aspect of her life through finding inspiration for new dance moves and actually guiding her movements on stage. The minigame is a simple rhythm game where notes appear from 4 points on screen and have to be touched with the mouse cursor when they're in the centre of one of 4 circles. Sounds simple, initially is, but with each dance the number, speed, and variation of notes increases to match Mata's ever-better dance routines.
Overall rather easy, requires about 5 hours for 100% clear for players well familiar with adventure games - newcomers may find some tasks difficult to work out. About the only downside is the crazy amount of travelling between locations in the second half of the game - nearly every step in solving a task takes place in a different city, and travelling between them (even using the safe trains) can be very repetitive and dull.
