This is a very interesting game. In this game, you will fight against a bunch of enemies, but you will have no guns or other weapons. The only weapon you will have is a round ball. And by shooting out this magic ball, you can kill all those enemies. 

You would find the whole process is rather satisfying, especially when you are in a bad mood. Every time when you kill an enemy, you will feel so relaxed. And it is a great way for you to vent out the depression and the negative energy that have been stored in your body. It is very bad for us to store too much negative energy in our body. 

It will bring detrimental effect to our health. So you need to release yourself from time to time by playing some relaxing game, which can serve as a kind of effective antidote to all those anger and negative emotions. There is no need for you to make any sense while you are playing this game. You can just shoot out the ball toward your enemies without blinking your eyes and without thinking about any consequences.
