Just finished it and I am loving every bit of it. The story, the mood, even the pacing feels great. Lots of questions that are left unanswered, with multiple routes to take for continuing the story.
Will the character (default: Aoi) be able to communicate with Sia? Will "Aoi" turn back into a person or will they live the rest of their life as a cat? What events will happen from all of Sia's actions? How will interactions with her "brother" play out?
So much be to answered. I am on the edge of my seat waiting for the continuation of it. Please continue this project. Look forward to this one and any others (SCP-999 project (waiting to see the blob)).
