I was reading the tips in the help section and one of them mentioned that theres an inventory, but I can't seem to figure out how to access it? Theres no keys in the keybinder that mentions Inventory, and pressing all the buttons provides nothing that I saw. I never picked up anything to add to my inventory yet that I'm aware of. Do you have to build something, like the clinic, to access the inventory later in the game? Like a storage unit? I'm really confused.
