Well this story could have been good if the dev would have made it like a real survival and not like a standard family with all the bad tropes of the genre.
The dialogues are absolutely not matching with the situation, it's weird. The mom who is supposed to be the badass scavenger behaves like a usual family mother, the sister is of course an awfull brat and the son is supposed to be 18 but behaves like a 10 years old kid with a first hard on problem !
This is ridiculous, if they really go outside they won't last one minute, this story should have been told in an usual world with a school setting, hmmm ehhh oh no not a school setting
