This has happened to me with several different games, I'm sorry to say, but it's always the same issue... lack of automatic save points.
For whatever reason, I've been playing this game for an hour or more without saving. Now, I save before boss battles, and before segments where the game says, "Oh yeah, this is a one-way door so you might want to save," or when I'm near powerful traps, but for whatever reason I haven't hit any of those triggers for a couple hours.
And then, without warning, I die. Loading my previous save, I find that I'd need to replay two hours of game to get back to the place where I was... yeah. Unless that game is amazing, that will win it a haiatus from me... a break that might well end up being permanant out of sheer frustration.
Petty, I know, but that's what you were asking about.
