Shoot Valium pills at Granny to keep her calm and in her Rocker until she reaches the Nursing Home. Granny progresses from calm Granny, to rocking Granny, to standing\stern Granny, to CRAZY Granny.
When Granny goes CRAZY off her rocker, she starts slinging desserts at you (cakes, cookies, pies, etc). You lose a life if you get hit by one of Granny's dessert.
The levels get faster and faster as you progress, and the harder levels also have an AMBULANCE that you must dodge (or you will lose a life).
I strongly recommend you turn the sound ON so that you can hear Granny trash talking to you (she's such a hoot), and so you can hear WARNINGS.
