This is a physics puzzle game in which you build Hokkaido by piling up prefectures of Japan. You become a "big person" and drop prefectures into a box. Connected same prefectures will evolve into a larger prefecture! Create the largest prefecture in Japan, Hokkaido, before the box overflows!
Does exactly what it says on the tin. The "Survivors" mode is cool, too, you choose prefectures, so you have to balance convenient shapes and sizes against random modifiers, very nice
