Only ended up playing one really solid run as I'll likely return to this game long after shiren 6 is out, from what I've played so far though it felt "too easy" in a bad way. It's possible I've just gotten better over the years but even at its worst, the day/night system that's very brutal in 5 felt like light work as new abilities are gained every so often through leveling up allowing for less panic scenarios where typically you wouldn't have abilities filled. And damage taken was low across the board especially from night monsters. Shiren the Wanderer 4 appears at face value to be worse than 5 in every way and I'd rather recommend new players to play 5 as the difficulty is part of the journey.
