The controls seem overly complicated, and things like running out of arrows, having to make a potion to survive in the cold, having to remember where the hell I can cook food, having to figure out where your horse is are all incredibly time-consuming and frustrating.
Well for the last two items you can simply visit a stable and summon your horse. No need to return to where you left it in the wild. Those stables should all have cooking fires as well. I totally feel your pain in terms of arrows though. I really wish there were a way to craft them so I could at least stock up when I'm in the middle of nowhere.
