This is a very simple game concept of 2 player shares one screen and keyboard to control their star-system-like geometry complex and fight with each other.
Player character is a circle formed by 6 random geometry objects surrounding at the centre of the circle. Apart from moving around the environment by using WASD keys (or direction keys), player can also press FG keys (or NM keys) to rotate geometries in the edges. The different shape would have different effects when they contacted each other: ball erases triangle, triangle erases square and square erases ball.
