You start as a energy ball and there are two humans on the top and right that shoot out other humans! If you hit any of the humans you lose the game. There are rectangles with arrows and if they sense movement your energy ball will move in that direction. The goal is to survive as long as possible, and you can test yourself against other peoples scores! There is also ghost mode (activated by a button on the top right corner) which makes you invincible. Ghost mode lasts for 10 seconds but can only be activated every 30 seconds. The humans move faster over time so it will get harder and harder. Your energy ball will slowly move to the centre so you have to always be alert.
