In the past, this brick busting-thing was a way to clear space from mines. Now it's an intergalactic competition, and of course you've entered the contest.
There are 170 levels and 4 difficulty settings, each of which must be cleared of all bricks in this shareware game in the vein of Arkanoid. You control a bat at the bottom of the screen, which must stop a ball as it comes towards you and direct in back up the screen, which is where the bricks which need destroying reside. Helping you out are bonus features including extra balls, bombs which clear all surrounding bricks, and fireballs to remove blocks quickly.
In the main menu, you can play with the balls inside the "R" structure to the left by touching its sides.
Try to insert all the balls in the most right-bottom part of the "R" and get a nice little morale boost from the developers.
