/*
short gaming manual:
There are three different parties a player can belong to: victim, chaser or killer
Every player starts as chaser. As long as there are not enough victims and killers, you can change your and other player's parties by shooting them.
In order to win you have to earn as much points as possible:
- as victim by escaping the chasers
- as chaser by shooting the victim
- as killer by killing the chasers


What you shouldn't do is shooting at players of your own party. By doing so your score will decrease.
P.S: If you don't want to be a victim: Get rid of your part by shooting a chaser.
