I think you should add blood wean you get hit and other things get hit(you can toggle in menu)when thats on you have no harts.also when thats on zombies when the bite you you turn into a zombie but you have same skin with red eyes and blood.also when you die your body stays on the ground after that you turn into a zombie(zombies cant break blocks and not kill other mobs.if you do it thanks.
