Related to this question, and on the Darkest Dungeon Wiki link here, it mentions that there is a stress penalty for backtracking (walking from right to left, using the 'A' key), and I'm trying to figure out if there is an aspect of the game that makes this penalty worthwhile. In other words, is there some benefit to getting partially through a hallway but not entering the room at the end of the hallway, so that turning around warrants a penalty? One obvious answer is that you could avoid a battle in that room, but you would also be avoiding any treasure that exists as well.
Just trying to understand the mechanics of the game. There are lots of guides with tips and tricks, and understanding how the game works is a big step in being successful (or not failing as much.)
