Nova Chain is a very unique puzzle game that will keep you trying to beat the levels over and over again. The objective is to burst the appropriate amount of spheres with only one click. The game is fairly easy in the beginning but it gets harder and harder as it adds more and more things to the game. Initially, you will simply click in an area to create an explosion that will set off the floating spheres. Later, there are timed explosive spheres in which your click explosion sets it off and it must be timed just right to explode the other spheres.
