Cubium

A bit copy of one popular game called Blosics 2, but it doesn't matter at all. It bring some new things as different types of balls. Your task is to get enough points by shooting down green cubes. When you push down red ones you lose the points and the blue are neutral. You can use three different balls. The first are normal with no special effect, the second type explodes creating a blastwave and the third makes the same but as implosion.
