Sprites are the graphics used by the games, normally grouped into one or several images. Many game engines include tools to split and manage those graphics in a convenient way, but this is not the case in React Native. Since it was designed with a different kind of app having in mind, there are several libraries supporting React Native in the task of dealing with sprites, but our game will be simple enough not to need any of these libraries, so we will store one graphic in each image and we will load them separately into the app.
