As I understand it, the whore mode is not finished? If this is the case and I didn't miss anything, then when will it be completed approximately?
Yes and no. All modes are playable to the end, but Slut Mode just loops back to the normal boss fight for now. Eventually it will have it's own fight and end scene, and possibly a few other art assets as well. I'll be sharing a roadmap with more thought-out time frames for new content in a week or so, but I'd say we're at least a couple months out.
