there's a lot of lore in the descriptions of objects/monsters, but it's overall (imo) about Kid's recurring nightmares/reliving bad moments and memories and finding themself in the astral plane. van in the shop gives a little more insight if you inspect them, but it's a fairly loose story and meant more to be atmospheric/hints & not a super concrete lore/plot. I have some update ideas, etc. to expand on it, but this first version is just about a recurring nightmare where kid meets van (and their father Lord Dredd who runs the midnight tower)

for context: there was also a risograph-printed book called Kid Canary: Rolling in the Keep (which was a comic, with some panels requiring dice rolls). there's only 180 or so copies of that and it's not available anymore (I might release it digitally soon) --- it doesn't have a lot of continuity, but amy (a fish girl) is mentioned in the game and she is a monster in that book that kid canary hangs out with. the book is very different tonally though & more of an adventure time/saturday morning cartoon/80s LOZ animate series vibe haha.
