Thanks for the review. Finally someone who defeated the boss.
The zombies don't give big penalities because many people don't know bow to defeat the player and keep dying as a zombie (therefore the score would be almost 0, but obviously there are players who can do it). I tried to add the role swap to the boss but it's newarly impossible to lose, you could destroy the player in like a few shots. I will think about it and maybe add this in a next update.
