The graphical interfaces present three buttons (start, options, exit) and a window for some very simple graphic options, disable shadows that can drastically improve performance or disable the Bloom effect of the scene, as well as being able to raise or lower the audio effects sound. New options are expected to be added in the future. For now this will suffice.
Similarly when you press the exit button, a dialog box is displayed to confirm if you really want to leave the game, this happens in the same way in the x of the title bar.
That's all for now. :)
