You shouldn't really do that. You'll end up trying to please everybody. Just pick a theme and use polls for things like hair, clothes, who a specific update should focus on, but the tags and story should be all you.
Yeah I thought about it, I can't Just please everyone. It's either this or that.
The planned tags are:
Romance, harem and pregnancy (Optional).
I may or may not add ntr for Lily and Nadia but not for Nova. But as mentioned above, these three tags are the mains of the story.
Futa/trans is also planned.
