this game is about losing a pet, grieving for the death of the girl's beloved cat, I believe that she could not accept the fact that her cat was already dead, the skulls, the paw prints represented the dead, as she tried to brush it off continue her steps to find food and medicine for her cat. She cant leave ofc, she had nowhere else to go with her cat, it seems like there's no one else that could take care of the girl, the wet sounds represents the sound of the blood
