Changed "Keyboard" to "Listeners", added "bar follow mouse" and window resize event
Better way to check collisions with bricks
Added left and right parts in the bar (to change ball's direction and increase-decrease game speed)
Bricks stored in a 2dimensions array (to create many lines) and added color and hits attributes
addBricks() and remBricks(), used to add-remove bricks when window resized
Some improvements at "Pantalla Class" (included game speed) and URL to the base I used to create the game
