Magman

Magman is an action game similar to Dig Dug where you as the titular character attack enemies with your fire cyclone guns to attack the invaders for points. When you are near waking up dormant volcanoes it will cause them to erupt and result in bonus points being awarded. Your speed will slow down when you reach a fault which will make it easier for the invaders to attack. To confirm this, there are two types of colors: Yellow slows you down giving bad pep, Red gives you good pep. You need to take oil to pep up. If any of the invaders catch up to you, then a life is lost and once all of them are gone the game is over.
