Defeat Dr. Mayhem (5 Missions)

This game is consider on the Top 30 Hardest NES Games according to The Electric Frankfurter's website. Is tough to figure it out for first time players, you have a vast variety of characters and attacks. But somehow the game tells you what to do, except for the last boss fight. Surely doesn't shine for its music, but in terms of story it is definitely well design. Is sad that the combination graphics+music made of this a bad game.
