ShockWave is available for free on Google Play. You can find some videos and screenshots on SlideDB.
ShockWave is a wall-breaker designed for touch control. There is no racket, no up, no down. To make the balls move, players create shockwaves tapping the screen. Unlike classic breakout like, the goal is not always to destroy all the bricks. Each level define its own objectives: protect brick of one color, change the color of the balls etc. This make each level a different experience. Furthermore, a level editor give free rein to your imagination.
