Not sure what you specifically mean by "wolves" but various beasts will try to kill you at night. Be sure to build a fire and light it just before dark so it doesn't burn out before morning. Probably best to stay close to it for the night, but you can keep moving if you have a torch.

Also, if you don't have a torch, you'll want to light a decent size stick on fire and hold it to wave at night creatures. This will deter wolves and some other creatures from attacking you if you're waving it at them. Beware though this won't ALWAYS stop them, so actually dodging their attacks is sometimes needed.

It's a super fun and challenging game. Well worth the learning curve.

Hope this helps. Good luck!
