So exploring space in a similar style as Mass Effect, but with naughty stuff thrown in is kind of cool. That you can choose the naughty stuff to the own liking is nice. The plot isn't half bad either!
Now, where we run into trouble is with how hard it is to figure out the battles. They're super complicated, and even after playing for a long time, some parts still make zero sense. It's like asking a pig to fix clocks! When players start up the game, most (like 90%) are gonna look at all this and say, “Nope, no thanks!” That's mainly due to the crappy tutorial. But the fights aren't any fun, even once you sort of get them.
Intimate scenes got a decent setup going on, especially with that auto-function. But man, the text describing what happens is too brief and cold. It doesn't give anyone a happy ending... and was this not the idea behind it?
If you wanna attract more players, fixing the battle system is key. You could totally revamp it or even take it out entirely if that seems best. As for spicing up those intimate moments, adding more detailed descriptions and adding more random descriptions would go a long way without needing huge changes.
I rly don't know why you are adding all the new story and just ignores the elephant in the room...
