If you don't like Futa you can turn it off in the menu, this will naturally disable any objectives related to futa photos, etc. While you will be able to finish the game without futa being on, you won't be able to 100% the game. We will build into the game female x female stuff as well, and there have been discussions about including a small variety of male monsters if we get the time to build them. No promises on that last one though.

Fair enough! I'm sure the game will be enjoyable either way, and I'm not much fussed about being a completionist, heh. Would be neat to get some males in the mix, but I know that's not the plan, so it would be a fun bonus if anything. Focus on your vision first, for sure, and who knows what could come in the future. It's already shaping up to be great. :)
