One problem, imo, is that the movement system makes it very difficult to scout ahead. Therefore you have to lose and save and reload several of the fights at least once -- often more than once -- to figure out a surival tactic. Many encounters even seemed totally unwinnable the first time I stumbled into them. After several restarts I know that, with enough foreknowledge, and luck with the dies, it is winnable. But this method -- having to lose one or more times before being able to win -- IS quite frustrating.
