What's the Matter? is a fun and challenging twin stick shooter that introduces you to the periodic table of elements. Play as Matty Matter, a bit of matter, as he sets off on rescue missions throughout the universe to save other bits of matter in need. Crashed transport ships, lost vacationers and prison escapees all need your help. Progress through the periodic table of elements as you move through space and collect your matter friends. Maneuver your way through asteroid fields, around comets and near stars. Fight off numerous aliens, robots and other creatures.
