What does the Game Manager in Unity primarily control?

The Game Manager in Unity serves as a central point for managing the overall state and flow of a game. It is responsible for coordinating various components of the game, such as starting or stopping gameplay, transitioning between different levels or scenes, and maintaining the game's state across these transitions. This includes tracking progress, managing game logic, and facilitating communication between other systems and objects within the game.

By effectively handling game transitions and states, the Game Manager ensures that the player experiences a smooth and coherent flow throughout the gameplay. For instance, it can define what happens when a player wins or loses, how to load and unload scenes, and manage game pauses or resumes. This role is critical to maintaining the integrity of the game's experience.

Other options, while important to different aspects of game development, do not capture the primary control function of the Game Manager. For example, visual effects, network communications, and audio settings are typically managed by specialized systems or components that operate under the broader framework established by the Game Manager.
