Hint is just about increasing demon power and i don't remember what more.. which is I don't need it.. exploration with no guide.. unclear hint about characters.. not enough hint about side chara and NPCs.. random event always occurs without hint.. always trial and error.. truly masterpiece.. this is what I'm looking for.. the game that's so fucking good with good stories and challenging.. take three days to finished instead of 1 day like other game.. I wish there is more update after this.. this is great games
