I'm going to give a general response instead of replying one by one. Some ideas, like the enemy concept, have been on my mind for a while and will contribute to two new mechanics I'm preparing to implement. As for the mushroom group, I originally planned it to improve performance, especially for the AFK aspect, but I see there's interest, so I might add something extra.
Regarding the futanari theme, most enemies will be futanari. I'm still undecided on whether to focus solely on futanari or include women as well—I'll read your thoughts on it. As for the gallery and femboy customization, I'll add them once I feel there's enough content to make it worthwhile. For now, I'll focus on the core mechanics.
