Skunny - Save Our Pizzas, this was a very popular shareware game that was sometimes included with Pizza deals. For Example a Pizza franchise in Australia called Silvio's (later brought out by Domino's) used to include this game with large pizza deals on a 3.5" floppy disk.
Each game uses different controls, most DOS games use the keyboard arrows. Some will use the mouse , "Alt" ,"Enter" and "Space bar".
