Bowling Defence has ten levels for you to fight through. Your job is to stop an invasion of creeps and nasties by directing your bowling ball and blowing up the evil guys. The controls are mouse only, but you'll need to have a quick brain and a fast finger if you want to stop the nasties before they get to the bottom of the screen. If you get invaded by six nasties, your game i over! In the later levels, you can't really advance without the More Power, Launch Wave and Bigger Ball upgrades. With a few turns you'll get the hang of it and then you won't want to stop!
