Nothing says harem like a tentacle monster fucking your LIs... and sharing the LIs (sharing is sharing, man or women).
Does this game actually have a harem route at all? or just tag abuse?
Uh, I believe you may have posted this in the wrong thread. That sounds more like a description of Subverse, another game that takes place in space, but that's basically where the similarities end.
That, or Cryoxxx has got some freaky shit planned for the next few updates...
Edit : Wait...are you talking about Nyx "interrogating" Pip with her astral tentacles or Noel fucking her former head-maid?
For the Nyx/Pip scene, it's avoidable if you aren't interested, plus Pip isn't
technically a harem member (yet), and even if she was, it's not sharing if it's 2 harem girls together. As for Noel, eh...that one's being debated a lot.
