Great game, captivating story. My favorite parts were the conversations with the people trapped inside the marbles. Those moments of human connection with souls who know that they themselves can't be saved, but who nonetheless try to help you find whatever solace can be found in this broken place... I only wish that there were more of those conversations.
I'd love to see more of this world, but I understand if you consider the story finished. What's in this game can easily stand on its own as a self-contained story.
