When Nintendo discovered that their Mario sequel was too hard, they made that crazy-difficult version Super Mario Bros.: The Lost Levels and Nintendo reached into it’s junk bin of prototype games and pulled out Doki Doki Panic, changed the characters and created Super Mario Bros. 2: Mario Madness.
It never felt exactly like a Mario game as the movements seemed a little different, all this new plant life apeared in turnip form. The game’s big twist at the end is telegraphed throughout, but that doesn’t make it any better. After finally pushing through to the end we discover that the entire game was a dream in Mario’s little head. We figured Mario wouldn’t save the world all at once but a dream? That’s pretty much just a way of saying everything you just did didn’t matter anyway.
