From what I can tell it's extremely fun. The gameplay I can say that I like it, it's not boring like Rance's and I don't need to keep rereading tons of repetitive dialogs.

The story is surprisingly good. I mean, you don't expect an ero story to manage to be this good, but the erotic element is used very well, doesn't offend one bit and contains enough meaning within the plot and in the subtext for things to happen, and I mean even for the scenes of rape.

The characters are charismatic and some have an interesting background, and due to the way the game takes place there are many opportunities for great interactions with the characters, which is one of the charms here.

Not everything is rainbows however, sometimes the story can seem a bit silly and have some equally strange dialogue, in addition to the times it happens that the decisions are very bad in matters of script, however it still manages to be good and fun, and it is something ignoreable, except for some specific chapters that are very problematic.

With all that said, I don't see why not play or give it a go if you're after a JPRG Erotic. This one is very good, I can't say it's above Rance, but from what I played in the first game, I prefer everything I saw here.
It's a great story that tackles eroticism and lust, but in general it speaks of humanity itself as a species and its desires, the somewhat lame way along with the ecchi cliches out there makes things a lot more deleteable if I may say so. Some might not expect the work to actually have something to present as text, but it does, it's simple but valid and it works.
