So when I think about how long space connections are, I can very well imagine that if I reject some of the women to be with just one, It would cause trouble within the crew.
Everyone will have desires, regardless of whether they're straight or lesbian.
Therefore, it would make more sense as a harem game, since a lot of offspring should be conceived on a new planet, although lesbianism doesn't help, so at least bisexual status should be achieved.
Otherwise, an interesting story, good graphics, and good animations. With some minor improvements, it could be a long-lasting story.
Keep up the good work!
