Hurt Me Plenty - Survival Addon

Maybe some details or new things would be great, like for example that some mobs see you from a greater distance (this function that comes from afar causes a lot of lag on mobile devices, so that would not be very good) or that they see you from a distance. through double wall of any block. Also abilities to some zombies or something similar like that they can climb walls like spiders or that some explode after a time of being close to you to break the walls and that everything is more difficult hahaha, even that would be crazy!

Also expanding upon that idea what if you increased the difficulty when you kill the wither it multiplies the difficulty by 2 and doubles that when you kill the dragon or if you fight it the other way around also you could nerf the foods saturation and how much food bars it gives. you could add an animal that can kill your farm animals at night if they aren't covered in a barn. These animals can jump a fence. Also, another animal that will eat your crops if they aren't protected. Also, you walk slower backward or when at low health like at 12 health or lower. kinda like some java mods that were in FTB blood and bones that would be cool. you don't really have to but it sounds like an idea that had to be put out there.
