I Think it would be a great idea to use the crafting skill to make some contraption made of planks, where you can hang raw meat, and cover it with salt so that it won't spoil, it will act as a container and would need a carpentry skill of about 2 points, and a cooking skill of 1 point (So that the player would logically know a way to not let the meat spoil), and to collect salt, you could get it from convenience store, or if you have 1 point in the fishing skill, you could get it from the salt water in the coast, where you could ''fry'' the water on a fire place with a bowl, to get both purified water and salt in 2 inventory spaces, so you would have another source of renewable water. Thanks for reading, and post more suggestions in the comments below
