In this lesson, we will create a basic player class that will represent our game's hero - a small white circle that will be placed in the middle of the screen. We will use this player class to define the properties and behavior of our hero, such as its position, size, and movement. By setting up this player class, we will lay the foundation for our game's hero and will be able to render it on the screen.

Later on, we can expand and modify this player class to add more complex features and functionality to our hero, such as animations, abilities, and interactions with other game elements.
