After selecting a profile (there are three slots for different users) a cel-shaded 3D Dr. Kawashima will accompany the player when browsing the menus and will explain the minigames.

After selecting the most interesting ones, some components of the development team will go to Dr. Kawashima's Lab at Tohoku University, where every game will be played while monitoring its effects on the brain of the player.
