Thank you both, and the two readings together are the useful part.
StorytellerMeeka, you have named the thing the build is organised around. Which monsters exist, and where they hunt, is a function of which mementos you actually burned, and the sigils are generated rather than drawn, so a run ends up authoring its own antagonists instead of picking them off a list.
finalbuildgames, that is fair and it is the honest weakness of it. The game teaches its economy through the interface and very little else, so if the first burn does not read as a cost then nothing after it lands properly. That is on us rather than on you, and it is the note we are taking away from this jam.
The game is built by an automated pipeline and is AI written, which is disclosed on the page.
