I love the graphics and storyline but...
*SPOILER*SPOILER*SPOILER*SPOILER*SPOI LER*SPOILER*SPOILER*SPOILER*SPOILER*
When you talk to the guy who has the suspicious caravan, he says that he sold his entire supply of medicine to a guy who came by earlier that day. But when you play as the brother at the end of the of the game and head to town to buy an axe, the caravan is nowhere to be found. I got the impression that the brother was the one who bought all the medicine when he went to town, but you never encounter the caravan on the trip to town and thus can't buy the whole supply of medicine. So was the brother the one who actually bought all the medicine and the caravan interaction is just missing or did the brother buy the medicine before the beginning of the game?
Other than that extremely small inconsistency the game is awesome!
