Mario is invited to Peach's castle, but when he arrives Peach is nowhere to be seen. He soon learns from Toad that Bowser has once again kidnapped her. The Koopa King has also put a spell on her castle, imprisoning her subjects. So it is up to Mario to break the spell and rescue Peach.
This game is fantastic! Needless to say, it is the best game of Mario serie. The employees of nintendo have been shown to have a lot of imagination in the levels. Even here, however, another goal of mario is to rescue Princess Toadstool from the evil Bowser. To do this, this time the heroic Italian plumber has to recover from the stars of the magic square that lead to different worlds: the battlefields, haunted houses, castles, islands etc.. The peculiar thing is that the game worlds are many, colorful and imaginative. Once you will finish the game, you will want to play again for who knows how long.
I have nothing else to say, but we will have to congratulate the authors who have had a lot of effort to create this masterpiece.
