All of the artwork is really excellent! Limiting the booklet to black and white was a great decision.
You did a good job setting expectations in the Who's This Adventure For section. In The Hook section, I think the last paragraph is the most important info as a hook, you might want to move the section heading there and add a new heading "Backstory" or "Overview" up top.
The tide clock is a brilliant mechanic to add some variability to the adventure. The "Note to GM:" stands out in F. Bandit Fort, because there's no other GM notes in the rest of the area descriptions.
I liked that you presented the "Outcomes" right up front, so GMs would have lens with which to view the adventure.
I liked the overall theme/vibe and you did a good job of breaking up and presenting the information, without over complicating it.
