I think this is probably one of the best VNs I've played... the story is interesting, the characters are as well. (PS for anyone reading, this comment has some spoilers if you haven't played yet).
What I found most interesting is the relationship dynamics that really only play out if you start dating all of the women. If you only date a couple or a few, you don't get to see the expansion of those relationships (ex: dating lilly or celine and not dating the other one, you lose out on all the Lilly/Celine fall out and reconciliation). Essentially, the game actually becomes more interesting if you end up dating all the crew, than if you only try to date some of them. I bring this up because I honestly couldn't see a way that the MC could date everyone without being a villain, but you actually made it believable. I went into a second playthrough telling myself that this time I would select the, let's say, more "cruel" options whenever we're allowed to choose, because I thought that's the only way the character would make sense while dating all of them. However, I gave up on that less than half-way through when I realised you would be weaving all the relationships together (also I can't stand being cruel, even for a game lmfao).
I do appreciate that when you are cruel, if you choose those options, the girls get pissed off at you. I'm wondering if being cruel cuts off options of romance, or if it veers off into the girls being more submissive? (Kind of like the choice you can make with Jade).
I also don't know if you're interested in this kind of feedback, but I did see another comment bring up dating Thym. I was wondering if something with him could be unlocked, after you've successfully chosen a few things: my thought would be that after you've made it clear you're not a raging homophobe or transphobe (so with Raene and Ziv), and also after you've sucked them off a couple times, AND said you were open to receiving anal, that Thym could become a potential interest. That way, people who are fully not interested in that would likely rarely, or never, even see that option come up, it would only be people who've repeatedly shown interest.
I also thought, in terms of Vess, that something that could bring a little more realism is if her relationship option (or even just the option to let her out of the brig) would not disappear if you originally choose the option to get angry at her. I think what she did would warrant some anger, but I also think that her looking all pathetic in the brig would make the MC rethink leaving her in there. In the first playthrough, I must have chosen anger or whatever one that basically made it impossible for me to let her out of the brig before the whole arch thing, even though at that point I did want to let her out and I felt that that MC's (and everyone else's) feeling of betrayal had let up.
Sorry for the long comment. I know some people aren't super looking for feedback but the story was so interesting that I had lots of thoughts.
