That’s like one of the super grindy JRPG titles I have (100 hours or so to get through the story). To get all the achievements, you’d have to play through an absolute minimum of 9 times, because you need to kill the end boss without taking damage on each difficulty level, and they unlock as you go. But you’d actually be grinding bosses for ages trying to get them without taking damage…

The game was ok, but I honestly can’t see wanting to play it twice let alone 9 times… there’s definitely a reason almost nobody has those achievements…
