In our Oroboros adventure, our dragon is endlessly circling in the dark world and trying to catch its own tail. We tap the screen to rotate our oroboro. When Oroboro reaches its own tail circulation is complete and oroboro is born again. Along our journey, we will get a chance to try different oroboros. Progressing enough will bring you to the discovery of a guardian oroboro. Since some oroboros have shooting abilities, some levels might resemble an alien-shooter.
