Spaceball: Revolution starts reasonably enough, giving you a fair amount of time and patterns based on Tetris blocks. This is clearly just to get you used to the game since the difficulty ramps up in a hurry. What starts as a basic grid will quickly have obstacles in your way that force you to shoot around them, bouncing balls off the wall to get them where they need to go. And if that's not enough, the grid gets larger every few stages and starts to rotate in order to mess up your aim. Add in that the screen zooms out to make precise aim even harder if you take too long, and you can see where this becomes challenging.
