I find the NPC panels to be a little underwritten, I wish there was more character and flavour there to latch on to. Considering the 'myth vs reality' surrounding the Peartree crew, it would have been nice to have a couple sentences devoted to each of them that better flesh out their legendary deeds and how that differs from the interactions with them in person.
Similarly, the ACT structure is written in a conversational style that suggests options but does not present concrete progression or pacing. There is some suggestion to have a few encounters with the dolphin creatures, but what tools to use to differentiate them are not provided. As a consequence of this, the scenario reads as one long violent sequence.
A cursory read of the pamphlet raised a few fundamental questions. What are the PCs fixing and how can those set pieces be made dramatic? What is some of the ecology of G'sliiit? How does the submersible spaceship work? What is the value of the sentient pearl in credits or rimworld trade?
This is especially frustrating where the text concerns the sentient pearl, its nature is vague to the point of lacking character.
Doris, however, is extremely distinct! I think the idea of being stalked across a submarine by a sentient dolphin and the alien life it is connected with is really cool.
The art design is very evocative. I especially love the map for the Peartree.
