For the most part, I consider hunger/thirst mechanics to be the cancer of the survival genre.

Nothing ruins a game faster for me than micromanaging a hunger and thirst bar. Eat some food, drink some water, move on and play the game for a few hours.

I'm reading stories about exhaustion from performing normal activities. Is that the case? Do I need to refund?

It's not a Rust/Green Hell kind of game where not eating will kill you outright. Food helps you in many areas such as surviving a tough fight and having enough stamina to attack multiple times and other actions. Right now the problem is that the food boost values are giving a headache to people who wanted less problems with the food boost values.
