exdefender
Classic arcade Defender, built entirely from glowing voxels. Fly the ship left and right across a wrapping planet, shoot the fighters and bombers, and rescue the abducted humans before they are carried off. Hits shatter enemies into tumbling 3D physics debris while additive flashes bloom where they land.
