There are two main types of gameplay here, and both are immensely enjoyable. The first is a standard, almost Legend of Zelda-like adventure in which Rocket must defeat monsters, obtain treasure, pick up items and solve puzzles using primarily his special Elasto Blast technique, which requires him to stretch out and launch himself at another creature or object. The other mode of play is something called slime tank battles. Early on in the game, Rocket will find something called the Schleiman Tank, which he will sometimes need to use to battle off members of The Plob or other opponents. In this mode, the top screen will show an image of the battle between the two tanks, as well as each of their remaining HP and statuses. Meanwhile, on the bottom, Rocket and his crew roam around the inside of the tank, looking for ammunition to fire and their opponent's war machine. Also, Rocket can leave his own tank and invade the other, destroying ammunition, attacking its crew and ultimately crippling its engines and winning the duel. All in all, the game is great fun, but the tank battles are especially so, which makes it all the more gratifying that the game also includes a local wireless multi-card multi-player version!
