What I want to achieve

In my own coding I want to take bits and pieces from most of my inspirations.
What I want to achieve from my own coding, is to have a circle chasing the mouse (you) with the click of either the left or right mouse button you produce random sized circles and squares which eventually lead to making it impossible for the circle to catch you.
The idea comes from the game 'cat and mouse' which basically has a cat forever chasing after the mouse. Which is what I plan to achieve in my code.
As seen below there are some sketches of my ideas on how it looks.
