Zirconium

An exotic alien species is invading our galaxy! The cubic zirconia, based on elemental zirconium instead of carbon, have tried to block your approach to their boxy mothership with their geometrically perfect space mines. You, as the intrepid space captain Joe Diamond, must think outside the box as you battle your way through their blocky blockade. Your ship's armor can only withstand a few collisions, so take good aim at the obstacles and don't miss the power packs spread throughout the galaxy!
