Yes, the succubus update!!! She's finally back. I remember she was there as a option to enslave i believe but it wasn't implemented yet so you couldn't do it. Though I'm not fully sure if i just missed it or didn't meet the requirement for the scene so it probably was still there.
Anyway, I've played through most of the endings i believe except for the Death one and i believe the Mom/Sister and Mom/Aunt(?) Vanilla threesome endings. I did the Sandy(Solo/MB(?)), Drow, Orc, Mom(solo/MB), Aunt(solo), Sister(solo) etc...and seeing as this is still being updated, i hope there's a chance for the Commander as an option as well as The Witch in the forest.
Between this and now The S.h.e.l.t.e.r(which irinia got me to play in the first place) this Dev might be one of my favorites as i love both of the games he's created.
