In my opinion, the "Big Brain Academy" in addition to Dr. Kawashima should definitely be in every DS Collection. Although Kawashima has a little ahead, but also the training with Prof. Lobo makes a fun time. Unfortunately, there is unlock anything, but then what screwed the long-term motivation pretty down. At some point you have just made each exercise 100 times and sets the game apart. Nevertheless, the game is good and I would recommend it definitely!
