2. I guess I see where you are confused about Katsumi's sadism and interest in BDSM, but it does help to have a good knowledge of the BDSM culture and community. Katsumi's sadism is a very big part of her character to me and is definitely explored more in the full game. Just the way that she can be invasive and demanding, she does a lot of power plays quite often. She's a tease and playful and sometimes you can't help if you get off on someone else's pain. You'd be surprised by who is actually into BDSM in the real world. It's also important to see that Katsumi is not only a dominatrix, but a healthy and good one. I don't won't the BDSM community more slandered and misunderstood than it already has been, especially with the whole 50 Shades series. I suppose it's not really bravery and impressiveness on Katsu's part as much as it's entitlement and narcissism. She's not a delicate person, she pushed someone down the stairs and shoots arrows. She's actually pretty rude, while calling out on other people to not be rude, but she's a protector at the end of the day, and I find that to be an important trait to have in a Dom. It's actually because of Katsumi that the twins' mother is out of the picture.
3. Yeah, I see where Yoko seems like just a wannabe badass show off, she's just an incredibly depressed and manic person that needs to feel strong or just need to feel something. But her depression isn't what should make her lovable, so I get it.
4. Quiet and avoids interactions, for sure, though I definitely wouldn't say she's shy. She just wants to avoid trouble. Suki just came from being horribly bullied and heartbroken and so she just wants to move on and avoid people. She wants to keep her focus on one thing.
6. I definitely will fix any bugs. The sprites, however, I won't redraw any of them, though I will touch them up. I am a one man team, and I don't have the patience and time to work on those. For the future games, I will have nicer sprites, but for 1.0 The Royal Rebels, it's not something that will happen. I also am not going to remove the BDSM for a number of reasons, one already being stated in #2. The other reasons are because that I already have all the art done for that and I would have to replace them with new stuff. Everyone has a sex scene and Katsumi literally cannot have sex without BDSM. She has a paraphernalia, meaning it is the only way she gets off. So removing the BDSM scene would mean removing the sex scene for her altogether which would make her path even more uneven than it already is.
9. The actual true story of The Illness Called Love involves queer polyamorous yandere magical girls and (a) demon(s), so there actually will be fighting and a conflict, unlike the visual novels. The visual novels are more of fluff to introduce the RPG's characters and theme. It is not the true story past the introduction sequence.
And as for the polyamory, well, the polyamory is important to me to have, especially since the relationships are important to see between the girls. As Chiaki in the beginning said, the polyamorous routes are actually closer to the trueness of the story. But it's important to the true story of the true game, as these are more little introductions and samples of what The Illness Called Love will be.
Thank you so much for your comment, though. I definitely will keep that in mind for 2.0 The Bloody Bows and 3.0 The Destructive Divas.
