This game proves that gameplay is king -- not graphics, certainly not substance, but gameplay. Who cares why you have to jump over a hot dog on wheels, or land on a giant floating banana? It doesn't matter, it's just fun to do.
The gameboy needs more of this type of game -- mindless mini-games that you can pick up and play for ten minutes while you're waiting to get your hair cut.
The diversity of the games really shows through too. Considering the constraint of "what can you have someone do in five seconds or less", they really packed in a lot of variety. I tip my hat to the game developers on this one.
