If we judge the game objectively, it's a very good example of a Japanese game. It's clear that the author really put effort into his creation. Dialogs, UI, scripting, maps, characters... It's not just another product to make easy money. If you want to immerse yourself in the world of a lustful village with your (future) girlfriend, I definitely recommend it.
However, I also would like to judge this game subjectively. As a sick pervert obsessed with NTR themes, I expected MUCH MORE from this game. In a village engulfed in debauchery and slave rules, there are only vanilla scenes and a bit of cruelty, which, however, is not revealed and not explained. If you want to play this game only for NTR - don't bother, it's not worth it. There are only a few scenes, and they're not better nor worse than in any other JRPG.
Nevertheless, it's still the best thing I've played in a long time. I wish the author all the best, and cross my fingers that the next game will be even better.
