It would be nice to put more details for the "survival" part of the game. I think about snowshoes when you go out in the forest wheres there's no trail. Without those, in winter, your character can get stuck in the snow. When it happens, the character may suffer from cold way more and will be slowed when trying to walk or run.
Also, it would be nice for exemple, to add some big winter storm, with blizzard, where you need to hide your animal in a barn to put them in security due to the cold.. it would add a little difficulty to the survival game. The winterstorm can put some trees in the street and also, can fall on a house. Then, you would need to rebuild a house or building and injured people..
It can be an random event.. that happens anytime.
Now, for the rain, it can be cool if we can get rain coat, and other things for when its raining. Without these clothes, the character may suffer from flu and other illness. As he get wets, for exemple, if he/her only wear basic t-shirt, the corporal temperature will get colder, so you'll need to get dry with a fire for exemple. It would be nice to add a clothes rack, to put some clothes on the rack to get em dry. ( can also aply in winter with freezing rain in the last days of winter as it gets hotter, near of spring ) . We could craft some to our villager in their house, if we dont want'em to get cold and illness too.
