Pacman In Space

Our class assignment was to take the book scenario Circles and make it better.
I decided to make a game out of it, and the first thing I came up with was Pacman.
I drew the Pacman and the ghosts in Photoshop.

Controls:
Left click on the world to create circles.
Circles will be created at the location of the mouse.
When created, the circles will also move in the direction that the mouse is moving.

Use the left and right arrow keys to control Pacman.
Each ghost has its own behavior, but all should be avoided.
Eat as many circles as you can, once you 25, you win.
