At this stage, I have no plans for male on futa and futa on male content. I am just not a fan of it in general and feel too many futa games take that path when futa is involved. All the other options you have listed are planned in the future.
I understand if this is not ideal for many, or the common approach when it comes to futa games but I wanted to create a futa on female game.
At one point the MC was planned to not be in any scenes at all even with the other girls but I revised this and now have plans for the MC to get some scene action and the futa will most likely be in them scenes just not on each other at this stage.
Sorry if this is not the type of content you were hoping for and I thank you for trying out the game and showing an interest.
I have had some time to play, and you brought up my biggest criticism so far, and that is the lack of MC on harem because it gives the feeling of the MC not actually being in any kind of relationship so far.
I don't have an issue with futa on female, and the content is kind of what I expected especially this early in development.
Some things that need to be looked at:
The quest system seem to be buggy in this version such has stacking quest objectives, no real dialogue to indicate the quest was successfully finished when submitted to the guild, and some other things that may be story overriding the quest.
An around the time you get to Eversea after the first general, there seems to be some lag, I don't know if this is a memory leak which I can check in a few minutes, but that may need fixing has well.
Edit: Just loaded the game and the lag is gone, so a memory leak causing performance decay for longer playtime. takes about an hour and half I think to become noticeable.
