    Brick Breaker

    Brick Breaker

    A Java remake of the classic Atari game "Breakout"

    This game is a clone of "Breakout", a game in which the player controls a paddle that is used to bounce a ball that breaks blocks. Items are occasionally dropped from the blocks. The game tracks the player's name, lives, level, and score as well. If the player scores high enough, they are placed on the high score board, which is displayed at the end of every game. There are an unlimited amount of levels, and the user can also select to have background music played throughout the game. Catch the green items to make your paddle larger, and avoid the red ones!
