(Yes, Hi! You can read my comment if you have never played Echo before as it doesn't contain spoilers!)
This VN is really intense, but I am really a fan of story games with adult nature, and this one was a the one I was looking for.
The story Is great and follows up with events, character backstory, and people though text perfectly! They were even moments while reading where I remember some things during the story. I've really been a fan of Echo Projects games for a long while and this one really kicked it off!
