SPOILERS!!!
The setup is very scary! Getting snowed in and the looming threat of a murderer on the loose had me quite tense the whole way through. However the final fight wasn't all that hard, since I had to fight like 5 different wild animals before I got there XD Joan is a battle hardened girl at that point!
I think the combat would be a lot more scary and tense if the character doesn't heal immediately after an encounter ends, so I have a reason to manage my resources instead of spamming attack like a maniac... Well, I did play as Joan so I imagined a neat little scenario in my head, you gotta love when girls are allowed to do violence!
There is a bug that occurs whenever you try to escape a random encounter and fails... It gets stuck on the next turn but no text appear, and you can't move or do anything. I had to reload my save whenever it happens, and ended up just spamming through combat instead of escaping later on.
In all, I think this game has a lot of potential! I think it'd be very scary if the combat aspect were adjusted, but overall it's a very neat short game. :D Good job!
