One of the best games for the DS
The way the game was made is very good, it is easy to follow the instructions and learn how you are supposed to act. But at the same time it is not that easy. From each operation you pass you learn something, like a new method, and the next time you face this problem, you'll handle it on your own, and each time it gets more difficult.
After each operation, you are rated, and there is another mode - besides the story mode - the "challenge" where you can redo the operations you already succeeded in the story mode in order to raise your rank, so, trying to succeed in all operations with a rank S, will give you a lot of extra hours of tense and fun gameplay.
The proprieties of the DS are well explored as you use the touch screen all the time, during the whole game. The graphics are really good and the story is interesting. It is a very different game that will surely entertain anyone (e.g: my brother is a doctor, a surgeon, and was also enjoying himself playing this game).
