Thanks for that. It is nice to see where the ideas go to.
I would love to see more difficulty options. Sure enough the first few days you may die, but after a week you grind XP on them, and only real big hordes are still an issue. After day 100, nothing is challenging anymore.
Perhaps a slide factor on the Blood Moon Spawns. That they get increasingly ferocious ? Was playing on difficulty 4 with 125% spawn rate, and still could manage a normal horde by myself, and 3 of us could handle a feral horde.
Also, the rate at which one become thirsty and hungry should also scale up with the difficulty.
I'm just spitballing here, but perhaps some more ideas can evolve on making mid - end game more challenging in the future.
