Oh I literally just opened up my notes, which I'd neglected for several weeks. I just need to "playtest" (roll some dice) and do layout, I am basically done. It's basically mechanics for crafting when you don't know what you're doing, which are likely to lead to interesting misadventures that need to be put right.
I've also separately, not for this jam, been working on combat-optional journey-generation mechanics, so I'm very curious to see the approach you take!
