Hi g_o, thanks for the feedback! You are correct! They are, indeed, meta-instructions. If you spend a lot of time in the tabletop rpg space, then this would (in theory) be playable with only what is here. But, as I say in the document, this is both an intuition and a version zero, so I don't expect this to be readily playable as it is.
I came to the jam really late and so I didn't have very much time to develop the rules into something complete (or even playtest them! I have no idea how balance would actually work out at the table, for instance). I borrow many mechanics because I was using them to think through the central intuition inspired by Jean-Paul Sartre (the freedom mechanic, which is my own). And since this was a philosophy game jam, I was more concerned with getting the philosophical framework written down than having comprehensive rules written.
I hope to work on this more in the future, so maybe one day I'll be able to provide you with a better recipe so that you can satisfy some of that rpg hunger! Thanks again for the feedback.
