SPOILERS AHEAD
Evaness was definitely my favorite character. I was really surprised by the twist but it didn't feel unnatural, especially in the light of the "bad" ending. Yes she wasn't mentally well, but she was still human; she still did good. I really liked the balance of it. And I can't imagine living through her eyes. Seeing the darkness encompassing everything, shadows dancing through blurs of chaotic light. It would drive you to insanity; it would drive you to do anything to change it or at least have someone else understand. The transition from being a likable and funny character to her madness didn't feel unnatural in that sense. I felt like Westwood: yes surprised and betrayed, but not in denial. Maybe it's just me, but I preferred the "bad" ending a lot more. Evaness (cool name btw) seemed to be recovering. Maybe she and Westwood could have worked together to figure something out in the future. I think her character still has a lot of potential.
Also, the music fit perfectly for this and so did the character drawings. I definitely got too emotionally attached to Evaness, Westwood, and Rogers. This and Beckoning are probably my favorite games of yours so far (I'm just missing the last two GANA ones). I can't wait to see the plot further develop!
