Sixty Second Shooter

A lone tetrahedron must battle an endless onslaught of cubes, spirals, corkscrews and other procedurally-generated abstract shapes as it descends through glowing cylindrical level portals and collects cross-shaped multipliers - all in sixty seconds. By creating chains of destruction the tetrahedron earns the CHAIN MULTIPLIER, causing cascading damage as exploding enemies in turn blow up more enemies!
