When this unusually titled, $40 game was released, it collected 96 5-star reviews [on Amazon alone] along the way. And I agree.
This 3DS game, besides taking an average of 5-6 hours to complete, is very similar in gameplay to the game before it, Kirby Triple Deluxe.
I give this robotic game 4.6 stars because of its short but sweet plot, and the actual gameplay is similar to Kirby Triple Deluxe.
