This is a very simple Brick Breaker game.
Shape classes in the SwingShapes package came from here: https://github.com/SER120L/SwingShapes.
Press the A key to move the paddle left and the D key to move the paddle right. The goal is to keep the ball in the air and have it hit all of the bricks on screen. If the ball hits the bottom of the screen, it is game over.
The main method for this program is found in the Main.java file.
The GamePanel.java file is the "engine" code, while the GameLoop.java file has all the actual game logic.
