Firstly, I just want to say that I love seeing your feedback on other people's jam entries, its really great that you're engaging with the community :)
I love the art vibe for this piece. Very murky and evocative. Like the underwater setting the game takes place in. Very fitting. I also like the idea that over time, the mortals gradually get tricked/trapped in the faweater. I also like that the fae look like the places they inhabit and players are encouraged to describe what their fae looks like.
Would be nice to have: A printer friendly version. But I can't think of anything else. I suppose maybe random fae generating tables so players can roll up what their fae looks like/resides perhaps but it certainly isn't necessary.
Cheers
