Hi! Don't apologize for the long comment, I'm glad you're excited about the game :)
I do plan on eventually having an aquatic anthro or a scalie introduced, but I want them to be introduced right. Not just for the sake of it, but to fill a role (as all our other characters do right now). When I can think of something, then I will defo implement it!
In terms of futa stuff, there will likely not be any. For now, the only character who is Femboy/Futa Adjacent would be Morgan.
