Really enjoyed it! I've unlocked all the endings and had fun with my time spent with the game :D
I've run into one issue with trying to unlock all the cgs, despite following the walkthrough you've provided, I can't seem to trigger Celia's farewell? Even when starting a fresh save file?
Real excellent stuff. I held my breath for nearly the entirety of the last chapter...the sense of mood and the way the journey progresses, the way the spaces look - it's so eye-catching and great at making the world feel larger than you can explore.
Really fantastic, wonderful atmosphere and the writing and story had a really nice flow to it, especially the character's interjections and responses. Lovely stuff!!
