Today's game was originally built by Steve Wozniak and Steve Jobs. It's Breakout, using P5.js.

• I can see eight rows of bricks on start, with each two rows a different colour
• I can move the paddle with my arrow keys
• I can use my paddle to hit back a ball
• I can eliminate the bricks by hitting the ball against them
• If I miss the ball's rebound, I lose a life
• Once I hit the upper wall, my paddle shrinks to one-half of its size
• I can see my score
• I can earn points for every brick knocked down

I don't really like that the ball is simply changing its Y position when hits the moving paddle. If the paddle is in move when the ball touches it, the ball should have a slightly different direction depending on the direction of the movement.
