User Summary Grey Cubes is a 3D block breaking game, with a premise similar to the classic Arkanoid, but with a twist. When blocks are hit, they bounce around before being destroyed. The player controls a paddle and ball throughout 60 levels, with a set of lives. If these lives are lost, they can be regained by giving up points from the score. Beating a level requires destroying every block that can be hit. Power-ups affecting the paddle and ball are spawned along the way to help the player achieve this goal at a quicker rate.
