There's a chest in a cave in the ice area that seems like maybe it's a puzzle or maze of some sort to reach it. there's an open doorway, but when you go through it, you can't see where you are anymore, but it also doesn't seem to go back very deep. Can you get this chest? is it an error?
another minor error is I got the horse and armor for Johannes before I got the letter, so i never got any dialogue about what the horse and armor was for.
Overall I think the map is interesting, but there's not much to do on it and none of the enemies pose any challenge. I really liked your last game with all puzzles, I hope as you develop this one, we'll get to see some of the same kinds of things.
