I've been playing Raging Loop recently. If you know what Werewolf is, it's that but in a visual novel format and with a time loop. Our main character gets lost in the mountain and comes upon a remote village that is soon after beset by fog. The next morning they wake up to find people dead and he learns that when the fog falls, it starts essentially a game of Werewolf, with some people with special roles working with the normal people hunting down the set number of wolves in their ranks while the wolves kill at night. Its also really smart. The main character, contrary to usual visual novel protagonist norms, is rather intelligent.
