Well, about honest feedback.. I know that futa is the main thingy here, but for many people it is a heavy point to not to play the game. I think, it‘s better to be optional. This way you will have more fans from both sides.
And it will be cool if you add more species into the game, like futuristic elves, orcs, etc. With different races it will be more funny and playable. Like those new japanese isekai novels with space thematic. Also, about some time I had an idea that it needs something like evil mc’s clone antagonist
