I really love Cass' character design :3 Well, everyone looks great, it's just Cass looks extra cool :D And I also thought MC's little sprite was absolutely adorable ^-^ I'm used to seeing either no MC at all or just MC's face, so it was nice to see a little more of them and their Halloween costume as well. The choice of pronouns are much appreciated too! Oh, and the text box design is also very attractive :3
I haven't exhausted all the choices yet, but I did reach an ending. I wish you luck with the updates! And a very happy Halloween to you too ^-^
