TLDR version
Pros
-Characters and most scenes are well done.
-Personalities of characters are different enough, they don't appear to be carbon cutouts.
-Differing paths.
-Music done right.
-Some of the best animations I've seen.
Cons
-Some throwaway scenes have the worst editing I've seen.
-Navigation, although some quality of life elements have been added, feels like ass.
-Nitpicking, but we see the occasional grammatical error.
The following tags are heavily emphasized
-Harem
-Femsub
-Romance
As such it's probably one of the most mainstream games available. At the same time it tries to do things differently so it feels like a fresh experience rather than a rehashed attempt at something we've had several times.
Normally when you have a large open world with day/night cycles you expect it to be horrifying. On top of locations on the map used to get to other open world maps (train to mountains) there are different direct maps between town and world and locations where you have to go to go to other locations. The three current big ones are the town, world, mountains. An example of where this might feel frustrating is in the home, you need to enter the living room to get to the garden as opposed to just having a garden navigation tab. There's also other issues, such as going to morgana's home, going to the nexus, from the nexus going to one of 5 characters homes.
It would really, really be so much more convenient if the author implemented a system to navigate easier. I will grant that this game is incredibly well done in that it doesn't just spam 50 locations at you, but rather it slowly adds them to the game so you get used to them as they come.
A nice option is the capability to mind control them to love you or dominate them.
This game has some of the most fluid animations I've ever seen. It's not even just sex, sometimes the characters will just walk around excitedly and the motion will be what triple A games are expected.
Without spoiling anything, a scene in which the editing is awful is when you meet a certain Earth Elemental on your way back from a place with a nexus. If you look at the background for a split second you'll never be able to unsee it. It only appears once, but boy did it leave a mark.
Overall, the good stuff far outweighed the bad. The worst part of this game felt like the navigation to me.
Anyway, there's tons of content and I absolutely would recommend this game.
