Thanks for all the feedback! I'm not sure what happened on the 4th day unless an Orc you didn't notice spawned close and got you? It's possible there's a bug but I haven't seen or heard of one like that yet.
Yes, the companion is one of, if not the best, feature so far I think! Where did it say the companion healed? I think that it just says it will collect reagents for you.
Yeah, the Orcs probably should spawn off of the screen...
Thanks!
