Classic Clash

Classic Clash is one of Dribble & Spitz's microgames in the Sci-Fi folder in WarioWare, Inc.: Mega Microgame$! (where it is known as Classic Clash III) and is also one of their microgames in WarioWare Gold.

Gameplay
The player controls a Mario-like hero called Nintenman, and must input a sequence using the only that appears above Nintenman's head to charge and fire a beam of energy at the Bowser-like enemy, seemingly vaporizing him. The beam has to hit the monster or else the microgame is lost, even if all inputs were pressed. In WarioWare Gold, the monster is remade to resemble a high-definition version of Bowser's sprite from the original Super Mario Bros.
