I would like to know as well, it definitely seems like it will be harem, but if there's gonna be NTR, I would like to know now and not waste my time.

Yes it's definitely harem, there will be more girls to come as well. NTR is not planned.
There probably will be one or two more "beast" girls, pretty much with beast ears only and human body.
Probably will have scenes with some "Monster" like girls, we are currently developing our fighting / questing system and that would kind of fit but we will see how it plays. (Might involve people from our discord and patreon in this matter)
There is (optional) bdsm planned but not implemented yet.
