Use the mouse to aim the tank. Click to fire. Destroy all the black dots before they get to the red line. Simple enough... Try and beat my record: 115. Another game like this: http://scratch.mit.edu/projects/13156947/
This is a hard game, for a number of reasons. The main one is that it'll take a number of tries to successfully destroy a ball. It takes a bit of practice, but all that extra hard work will get you...one point per ball. 02/11/2013: Power-Up #1: Bounce now finished.
