Viability: I'm having a hard time understanding exactly what I'm doing right now. I think I need a little more guidance to get to the end.
Presentation: I'm confused about the mechanics but things are color-coded and well thought out, So good UI, but some confusion with the mechanics.
Theme: I like your cryptic writing style. It creates a very mystical feel!
Engagement: Your writing is a plus as it asks the player to imagine much of the world themselves. Some context for gameplay would help me have more fun there however!
