Overall, HaremKingdom is one of the rare non-nukige VN that focuses on a harem route and harem endings. This is actually REALLY rare amongst VNs, I have read hundred of VNs and can't think of a single one like this.

With VN often being a route based medium, each heroine usually gets a route, and once in a blue moon we would get a threesome ending. Harems are usually found in Light Novels and not VNs. Below is my ranking for the various aspects of this VN:

Art: Amongst the upper end of VN art. Vibrant color + expressive sprites + decent number of costumes + distinct heroine design. The 1280*720 asset is a minus, however. The game could DEFINITELY use full HD assets.

Story: Good worldbuilding, with explanations about how the world works. Comedy is decent, quite a bit above the usual moege. It is a bit cringe sometimes though. Plotholes are all filled in routes.

H-scenes: 9/10. Good in both quality and number. Furthermore, HaremKingdom's H-scenes also have bedside conversations before and after the scene, which is great. Mosaics is the reason HaremKingdom gets only a 9 and not a 10.

Voice: Very well done and very expressive. The heroines are very expressive even if you don't know Japanese.

Heroine: All 5 heroines are distinct and likeable. Extra points for no lolis.

Truly the perfect coming of age adventure game. I'd recommend this VN to everyone who want a bit of H, comedy and adventure at the same time.
