Bevy exposes many features to customize the engine. Enabling them add functionalities but often come at the cost of longer compilation times and extra dependencies.
The default feature set enables most of the expected features of a game engine, like rendering in both 2D and 3D, asset loading, audio and UI. To help reduce compilation time, consider disabling default features and enabling only those you need.
