I'm 42 hours in and just starting the end game. There's still more side quests I haven't done. Really enjoyable. Likeable characters, amusing dialogue, a dramatic fun story, easy controls & UI layout. Huge range of combat difficulty settings from very easy to a serious challenge by turning Relics on/off that you buy in stores. No dungeons as such, but various short story locations with puzzles and end bosses. Huge variety of colourful detailed environment designs.
I've got everything on easy and hardly have to use any food recovery, get full health back after any fight. I tried with Relics off, then it's a challenge. If you like Golden Sun, Breath of Fire, Chrono Trigger, get this!
Many save/camp (recovery) points, but I just turn off the Switch and it continues at exactly the same place so long as I don't exit the game.
Recommended and worth it $50au
