PacMan Animation in Processing 4.3 Program

I am pursuing the development of a simplistic yet engaging PacMan-inspired Processing 4.3 program. I envision the iconic character performing the action of opening and closing its mouth within the setting of an open field. I will provide a sample video of how the animation should look like and you will write me the code


- Proficiency in Processing 4.3 programming language
- Experience in developing animations

The apt freelancer for this project should be capable of synergizing these elements into a flawless and engrossing PacMan experience.
