the short length and nonlinear structure of this game make it perfectly suited to short handheld sessions. as someone who has played world 1 of mario way more than the rest of the game, mario land 2 feels like getting six different versions of world 1, each with a creative visual theme that is unique for the series. of course, the tradeoff of this structure is that the game can't really build complexity over time, the difficulty curve is flat and there's no truly great levels, just a bunch of pretty good ones.
