I read through you jam entry. Here's my written commentary on your adventure content and layout:
---Good colour scheme, visually striking. Helps identify elements in the dungeon aspect
---Neat in-universe memo that can be treated like a handout or job offer
---Intriguing horror with the geology being sentient. How do you kill a landscape? Cool and thought provoking
---A bit of a Metroidvania aspect to the dungeon crawl, well integrated
---There is a Siren Transformation trigger in nearly every room, PC escape mathematically unlikely
