In each level, you have to find eight keys to unlock the door to the next level. You can collect carrots for more lives and there are various weapons you can pick up to take care of your enemies, including bombs, lightning, a cork gun, juice, and weights. Other items like a hammer or pick-axe can help you get past level obstacles.
Shields, clocks, and shoes will protect you from your enemies. As Bugs Bunny, you can walk around, climb stairs, use elevators, and climb through tunnels to navigate around the screen.
