There's nothing wrong with the illustrations per se, I just prefer to imagine characters based on how they're described in text and find that illustrations can break immersion when they suddenly crop up in an otherwise text-based game, especially if they're a certain style that's at odds with what my brain conjures up. I understand if you can't or don't want to make it an option to turn them off, and I hope you're not offended by the request, but I really hope you'll at least consider it, even if it means they're on by default and turning them off is something you have to do in settings.
I appreciate you adding the mod descriptions in future - it's good to know roughly what it entails and get a heads up on the downsides of each power, too, even if it's just hinted at! I will definitely do a playthrough of each type of mod when the story gets more content, and I love how aspects of the story change depending on what mod you choose. I love that sort of attention to detail, an the replay value that comes with it. Just FYI, even though the most tempting is mind control, satisfying our inner dictator lol, I decide to choose the one in relation to controlling the senses, just to see how it is. So far, pretty interesting!
As for Quinn, I did actually check up to see if she's a romance option, I'll admit. I was/am playing a gay male (so much for that lol), but I'm a huge fan of interesting and challenging characters first-and-foremost, and Quinn had me the moment she hacked away at my arm like a kid in a candy store, and then it was love when she called me Stumpy. LOL. But seriously, I know she's not a RO, but at the very least I better be able to give back as good as I get from her, and get a lot more weird, unpredictable moments with her to keep things interesting. :D
I'm also really intrigues to see how the romance with the enemy android goes. Enemies to lovers is always a fun one to play, all the rivalry and tension. That is definitely top of my list for playthroughs of this game! :)
Good luck for your future writing! :)
