-Players should have the option to enable/disable in-game HUDS that shows their health status. Even though I like minimalist/no-HUD approach, at least having the option allows players who like HUDs to have that convenience.

-The screen is quite fine in-game because it is minimalist and no-HUD (I personally do not like to see numbers, bars, etc while I'm playing as it loses the immersion). But I do wish they have some kind of menu or spot in the inventory where you can check your health status/statistics such:
a) % of hunger
b) % of thirst
c) degree of your body temperature
d) % of how much you are feeling sick
e) % exhaustion
f) % blood loss
g) % healing of wounds
h) % wetness (from rain)

It doesn't have to be quite stuck in the inventory menu, but at least a different tab or assigned to a different button that pops up a separate menu that shows your health status. It's quite impossible to guess if the player is sick (I've gotten sick randomly even when full and not having been hit by zombies). In real life, you just know when you are hungry, sick or cold, this game lacks ways to show you on-the-fly what you are feeling.
