This game has some of the best character renders and world backgrounds of any game (not just sexy games, any game!). It would be amazing to see what the dev could do with other settings:
They could have a fantasy setting with magic, elves, centaurs, etc. or maybe the player could have a time-machine that malfunctions and sends them back to prehistoric times (futa cave-women that all want to breed the main character, different tribes that you can work with, or be captured by) or to the roman empire with armour-clad futa and warriors.
The time-travel one could be called "Back to The Futa" instead of Future

or these could all be part of Star Periphery in a VR type of scenario. Maybe the player could get trapped in a Tron-like experience, and they have to service futa in order to escape the game.
Honestly whatever they decide to do, I just hope we get to see more of their brilliance.
