Hey, glad you enjoyed the new demo :) It takes two axe swings to the head to kill basic enemies or one charged attack, which I feel is pretty fair. Agreed the pistol is weak headshot wise, I'll bump up the damage slightly. It's good against enemies legs at least. Trying to distinguish the weapons somewhat, like the shotgun/crossbow are great at headshots, pistols good for leg damage etc. 

I could most certainly add a gameplay modifier tho, "Realistic headshots" or something where the damage is increased a lot.
