A play very simple... but not so easy that that! While time ravels, you must burst the bubbles violets (what gives you points) while avoiding bursting the gray ones (which removes you points). Ice floes ravel on the screen but are there only to disturb you. Especially how the bubbles violets ravel at a tremendous speed which it would seem almost impossible to touch one of them! Keep your calms because it is very easy to fall into a negative score!
