This was really cool, Gnosticism is a fun topic.
I've had fun exploring it in the past, when reading stuff in the Nag Hammadi library like The Gospel of Thomas or On the Origin of the World, and that shadow part felt very Jungian too. Letting the player interpret it in different ways was also a nice touch.
Sophia's design is really nice to look at. If only she had more screentime.
When playing, I noticed two images that failed to load: "aki_reflection_glitch.png" and "nc305063.png"
Overall, I enjoyed it a lot, it appealed to my nerdy religion-researching side.
