How to play
You will look like a a little person with a morning star. That is the best I can describe it. The way you move your character is either w,s,d,a, or the arrow keys.
If you are in full screen, to move your morning star, you have to click where you want it to go. If you are not in full screen then your morning star will follow your cursor.
If you hit another person with your morning star they will disappear and your weapon will get larger. If you are hit then you will disappear.
One tip is to hide in your own morning star.
