What is soul? What is life? What is there, upon death? Why are we all here? What happens when we leave? How to imagine the world where there's no "me"?

You know I'm really fond of all this "food for thought/brain" stuff so this game couldn't just pass me by, it got right into my heart and made me compassionate for the protagonist, for all the prisoners of Gehenna, for all the messengers, for Milton, for Admin, even for ELOHIM. In this game there were some moments, some parts of the plot when I just stopped playing and spent hours thinking of what I'd just read/heard. And there were moments I thought I would never continue playing it because these ideas from messages were incredibly terrifying for me. All this existential topics I always feared to discuss even with myself were brought from the inside and put right before me. And I had to overcome it again and again. The challenge is much more than one room with a sigil.
It's not just a puzzle game. It's some sort of a school. See -> read -> understand -> percieve -> solve.
