I've played this game almost every day since I bought it. If you like brick breaking games and arcade shoot-em-up games, this is a great combination of both. While trying to break all the bricks on a level you are also attempting to shoot down robot ships (25 robot ships gives one extra life). The robot ships are trying to put bricks back and firing missles at you, Some robot ships will dive at you kamakaze style. There are many power-ups both negative and positive...too many to describe...one example is a power up that causes the bricks to jump out of the way when you fire at them. It only lasts awhile. About every fifth level is a fairly easy "space-invaders" style round where you just shot everything that comes at you. This is followed by a very difficult round of robot ships attacking you with everything they've got. A great challenge. Can't give it five stars because they have at least three levels where the ball can get stuck in an awkward angle and bounce about 20 times before it gets unstuck, however, you just wait...I've never had to start a new game over this glitch. This game is well worth the Amazon price.
