TIPS: Grab the humans in a certain order to get more points. If you grab Mom, Dad, then Mikey, every human after that will be worth double the amount of points.
After grabbing any human start shooting the Hulks, because they're worth points until you get you next Free
Life. Also try wiggling the joystick around and see what suprises start to happen.
