I quite liked how you presented the Random Encounters table and the dungeon flow charts.
I definitely understand trying to save space with the limits of the game jam, but some of the text is a bit difficult to read overlaid over the images and the font would benefit from being a few sizes bigger. I really liked the cover as well as the image on page 12.
The Moonfire Moths and String Bonds were both good ideas with interesting mechanics. There is a lot to try and keep track of as a GM but there's also a lot of useful content.
