Check out Professor Plum with the Doomsday Bomb at Demonhead! No, it's not Clue. It's Clash at Demonhead, an action platformer in which you take on the role of Billy "Big Bang" Blitz, racing through a collection of side-scrolling stages to save the world. Although the mechanics are similar to other platformers, the game's open-ended and non-linear design makes it a great choice for anyone looking for a replayable NES game. This simple cartridge offers more than just two-dimensional platform action - it also features an intricate plot that takes you across the world as you scour the stages for the medallions that can save the world from imminent destruction by the Doomsday Bomb.
