I enjoyed this a lot more than I thought I would! I expected it to be quite short, but It was actually kind of long. I played through Lyell's route, and I really liked it!
The main errors I found (as of version 1.0) were that when Cecil was first introduce, Hazell shows up, but her sprite doesn't appear. And the other one I found was that in the first fight with Cecil, I think the instinct and reason choices are mixed up. You stay out of the fight when you pick instinct, and try to help Lyell against her wishes with reason. btw instinct is misspelled in both the fight scene, (And maybe others as well) it shows up as "instict".
I found a few logical errors too, when Lyell goes to Jamie to do... something... it's never actually stated what she needed to do there. Considering the conversation, it probably had to do with Cecil, but I don't think it's ever actually said. If it was I missed it. I also had a hard time figuring out how close Lyell and Jaylene were before the game. In the beginning nothing is ever stated that Jaylene knew Lyell from anywhere other than the dinner, but later Jaylene say's she's known Lyell for years. And even later, also says she knows nothing about her? I think I kinda get what you were trying to say, but it feels a little conflicting.
Over all, I really loved the game! and I'm really curious to play down Xanthe's route once that's finished!
