I just finished playing the game and honestly I loved it!
I must say that I'm a bit sad that the game is being abandoned though.
I still think I'll buy the book(s) whenever they're released because I love the story and the characters, but as sad as it is to say, I don't read actual books as much as I used to do years ago, and I think that now the same goes for a lot of people. It is most certain that a VN format would be more enjoyable for the greatest number in 2025, even just for the ability to see the characters faces and to have a better sense of immersion into the story.
Anyways, I'll try to keep up with the updates regarding the progress of the first book (even though I know projects like this take a LOT of time and it might still be a matter of years).
