This game is addicting while at the same time having an excellent ability to make you frustrated. The thing it lacks the most is diversity, though this can't really be held against it, as it's not claiming to be anything else then a 'simple' action/puzzle game. It's highly original and shines with simple yet brilliant design. Oh, and if you also have a friend with a GBA you will find that this game is quite a blast in multiplayer as well. Kuru Kuru Kururin comes highly recommended to all of you who want something simplistic, yet surprisingly fun, to spend your summer with.
