I finished this earlier today and I just...I have no idea how to put into words the absolute rollercoaster of emotions I felt playing Adastra, from the confusion starting out, to the shock I felt at the twists, to the genuine attachment to Amicus that grew over the course of the story, to the absolute heartbreak and sadness I felt once the game reached its conclusion, to the point where I was quietly crying in the middle of class so as to not draw attention to myself.
I guess what I'm trying to say in this rather poorly worded review is...I love the world that the Echo Project team crafted, the characters they created, the music, and the well-written, complex, and realistic relationship between Amicus and the MC so much, the latter of which was probably my favorite part of the entire game.
TL;DR: Thank you to everyone who worked on this and being able to deliver to us an absolute masterpiece of a visual novel.
