A nice mix of Kirby's shapeshifting mechanics and Mega Man's level structure. Doesn't do a whole lot to define itself, but I love the way most of the enemies in the game are actually completely passive - often minding their own business or merely nudge you around out of curiosity. For you to only take damage when an enemy swings at you, that's amore. Yakopoo is the cutest mother fucker by the way.

Edit: I think this game came out before Kirby's first use of the copy ability? Kinda cool actually
