Hello, I'm one of the people who was involved in this production~ Last time I spoke to Agashi was when I did composition for her NaNoRenO 2017 project. I just want to confirm that this project was indeed not a scam, and it was something she was certainly passionate about! I get the feeling she simply burnt out some time after all of the other staffers had completed their work and perhaps it's too disheartening to try to attempt to give updates when no progress has been made.
I can ask her about how it's going, but I reckon the answer is not very exciting! At least in terms of this project.
