SMB2 is quite the most unique 2D Mario game (because it is literally a reskin of a different game), but still a good game nonetheless. The game kinda feel like a fever dream in the Mario universe, which makes sense as the story is branded as Mario's dream. The biggest difference about this Mario game compared to the others is the ability to pick up objects and enemies and throw them. While I really like this mechanic and wish it was in other Mario games, it is something to this game's detriment. One of the most satisfying things about playing a Mario game is stomping on enemies head's as you platform. You can no longer kill enemies by stomping on their heads due to the fact that the designers want you to pick them up and throw them. Again, while I do like this mechanic, it does bring the whole game down by 1 point for the fact that it won't also let me stomp on enemies. Nonetheless, if you can adjust your expectations of how Mario works for this one game, it is still enjoyable.
