The Name of the Game Is...?

Ok, so there was this computer game that I used to play when I was in middle school (approx. 10 yrs ago), and I am certain there is an updated form of the game to play, though I can't find it so I'm asking if anyone remembers the game I am about to describe: Now in the game I experienced, my mouse was a "spaceship" of some sort...I was placed in a square stage where there were two balls bouncing around. THe goal of the game was to click your mouse (spaceship) which in turn would make a barrier of sorts come out of either side of the "spaceship", and this "barrier" needed to reach each side of the stage before one of the balls hit it, thereby destroying it. But if the "barrier" persisted across the entire stage, it cut off that part of the stage. The ultimate goal was to cut off the percentage of the stage that the level required you to without "dying" (a ball hitting your "barrier") I dunno, I know I can't be the only one who's played this game or knows what I'm talking about, help me out, let me know :)
