I'm not sure yet; I'll have to experiment and see! But multiple human/goblin girls are planned!
Of course! I intend to keep pretty much everything optional as it is now!
Currently, every update is a standalone. I am researching a way how to distribute only the update data in the future, but as I'm not particularly skilled in this matter, I have no clue if it will yield a result or when it will happen.
I don't plan on breaking everyone's saves with any near updates!
That said, I might possibly break it with the UI rework, but I don't expect it to be finished until the very end of the year. And it is still a big if, but considering the sheer scope of the changes, I'm afraid it is possible. But don't worry. If that is the case, I will warn you all about it in advance!
