Hi Jay! Sorry for the long wait for a reply. Thanks for the answers, all very useful. Re:typos, I see the game is getting printed already, but if you think you may, for example, want to update the pdf I can send you a list of what i found via DM.
Re: the play aids we made, it was a sheet helping us remember the available rituals. It gave us the ritual's name, what is it meant to do/feel/convey, and the starting ritual phrase. Given this was a oneshot, it helped us remember that rituals were a part of the game, and remember what specific rituals may serve the scene and how to start them - otherwise we feared we may forget.
In hindsight, I think having the exact same thing for the Setting Elements (maybe 4 columns with name, themes, "pick up when" and "put down when) would have been very useful, too.
Ours was a sheet scribbled in pencil, nothing nice I'm afraid - but I'd definitely say it helped us play and made the game more approachable/accessible.
