You are a naughty boy living in zombie-town.
You are now on the roof of a building in town.
Throw the balloons filled with water on zombies who are walking on the street.
But, hit only zombies, not human beings and you will get points.
You can move through the roof to aim for your target.
Make sure to duck down when zombies get angry at you right after they are hit, or you will lose one Life-heart.
Watch out for the police that will try and stop you.
Each level has a set number of targets you have to hit.
Hit all of them to get to the next level.
