I have a diamond sword and tungsten shield and still have a hard time killing the raiders with the horned helmets. They also walk over hills, through house walls and stone walls. I can't seem to kill or stop them. My only choice is to out run them.
The game is great and I gave it 5 stars.
Perhaps you could add some more furniture and maybe a fireplace. During winter it would be nice to be able to crack the ice to drink or fish. It would be nice to add some fruit trees or berry bushes that can be grown and survive more than a season.
You have a really great game, keep up the great work.
