Rabbit Software's Quackers is virtually identical to a shooting gallery at the fair. Ducks and rabbits glide across the screen so slowly that it's almost impossible to miss them, although it's almost more fun if you try. Slightly more difficult is the last part of the game where, having gunned down all the targets, you're given the chance to 'keep the turtle hopping' by shooting at it as it moves quickly across the screen. A few moments of gratuitous violence for all concerned.
Slap Dab and Traxx are both joystick compatible, but surprisingly, Quackers isn't. It does, however, let you define your own keys.
