Just finishing Part 1 and I really appreciate and have enjoyed the effort put into world building. The harem content is handled super well also. I do wish there was more interactivity though I admit. Choices are few and far between and when the adventure party is out doing their thing it would've been fun to make some of those fights playable.
Overall I like the story a lot. Only other real complaint I have is that it took literal HOURS of playtime to finally have somebody cut the MC's hair. I mean goddamn you're forced to walk around for so long, just looking like some kinda fucking medieval times Professor Snape. Hair looking like a chemically straightened greasy hair bozo.
