Blast Thru is a supercharged variant of those old arcade standards, Breakout and Pong in which you must use a ball and paddle to break through a wall of bricks to the next level. It has impressive sound effects, adrenaline-pumping music, great graphics (apart from a somewhat dazzling background), and wonderful gameplay, owing a lot to the preeminent Breakout variant, DX Ball. The wall consists of bricks with varying characteristics, some impervious to the usual ball. You'll need to collect powerups to break through all the bricks and advance, but you'll have to avoid powerdowns that can reduce the size of your paddle, speed up the ball, and cause numerous other disasters to befall you. The registered version of the game has 40 levels and enables you to create and save your own levels.
