I took a close look at this when it was the only submission up yet, not realizing I couldn't submit comments right away, and I've now lost my notes. I like the general concept and the sense of disorientation it fosters.
I think this amount of text in a trifold requires more effort on the design front to make it readable. Right now it'd be very easy to get lost in the wall of text, and I think many people would just look at it and go "I'm not reading that" before giving the content itself a chance.
In terms of content, what confused me most was the living coolant, specifically when and how often it should be "attacking." If it's just whenever the Warden feels like things have slowed down and needs to pressure the players, make that clear. Alternatively, it may have been your intent that the coolant-themed encounters are what provokes the attacks, in which case that could also be more clear e.g. "attacks every round until the players leave this area."
That said, the tables are fun and I like that the randomness makes it almost roguelike in that if the players were having fun but got TPKed quickly, you could actually run the same thing again without it being very spoiled.
