DSDN 142 - Good or bad idea?

Alright so... just thought i'd post this..
So first of all instead of circles I have made a new shape which almost looks like a candy wrapper.
I have done this to create something more exciting than cirlces bouncing... So I added a few squares to it to keep you interested :)

I have created a new funtion where if you press the mouse, the 'Candy Wrapper's' (circles) increase there speed.
CODE:

 void movement() {
    x = x + speedX;
    y = y + speedY;
     if(mousePressed == true){
     x = x + speedX+0.1;
     y = y + speedY+0.1;
  }
  }

I thought this was a good idea because it would give you more of a challenge to hit them away.
