One of the uses of Managix is that you can enter a room and load only what that level needs to function (sprites, audio, etc.), and after leaving the room, these things are released from memory, leaving you free to use in another level / room - You are responsible and have full control of what is loaded/unloaded. Besides, Managix allows you to save and load buffers, useful for saving and loading game progress, localization files, settings and countless things. And all of this is compatible with all platforms, you just need to setup once :D
