Agigongnyong Dooly Master System

Agi Gongyong Dooly is an auto-scrolling shooter based on the Korean cartoon Dooly the Little Dinosaur. The protagonist is a baby ceratosaurus who was kidnapped by aliens, brought back to Earth, and survived the Ice Age, only to turn up in modern-day Seoul. In this iteration Dooly has to travel to different time periods, defeating various unsympathetic characters from the cartoon on the way.

Dooly can jump and uses various firearms with unlimited ammunition to dispose of enemies. In most stages he is restricted to one type of weapon. The goal of each stage is to obtain three keys. Two of them are randomly dropped by enemies, while the third must be won in a rock-paper-scissors battle against a character from the cartoon. The stages loop indefinitely until two keys have been obtained and Dooley is taken to the "boss".
