The circle character 'D.O' has bullets and can shoot enemies, while the square character 'Nemo' can push or lift objects to help you progress through the game.

In Multiplayer mode, each player controls two characters in two screens simultaneously, with one controlling and each able to shoot bullets to destroy the competitor's robots. The game offers three themes to choose from, and you can enjoy playing with your friends by winning three out of five rounds.
