There naturally are non-futa women in the universe. You can see plenty of them in the backgrounds. But since this is a futa on femboy game, interactions with them are minimal - but they are there. Isabella, for example. On PS-10 (and Periphery in general), a large chunk of the population is futas, because they were exiled there. There are also multiple alien species with wildly different sex dynamics; for example, Tarnians (the big blue ladies) don't even have males; only females and futas. Others (like Pyrphera) propagate through different means altogether. You can read more about it from the in-game Codex, or from the alien sheets on my website (in the signature)!
It's mostly the angle and the fact that I started using wider lenses for my scenes, to give things more presence/allow better closeups!
I'm working on the fix, which will be out this week!
