Just had a shot of the latest build and so glad to see this excellent indie maturing and improving. A couple of suggestions:
I attacked a gang of outlaws and one of them was killed running into their own camp fire! Whilst this was funny (and you may want to retain for that reason), some improved AI might help. On the other hand - maybe give Outlaws/NPCs differing IQs with the dim ones doing stupid stuff like that.
Something that occurred to me when reading a review of Lost Dutchman Mine (one of this game's influences, if I remember correctly) - the cost of items is way off for 19th century United States - $5 for a pack of matches? It's a minor thing, but might want to consider a money system closer to the historical one.
Keep it up! This is going to be great when it finally leaves Alpha
