make no mistake it's obvious that you knew what you were doing; but it's just unfortunate that it isn't accessible (although to be fair, the more you delve into tabletop rpg the higher the entry bar). still, i see a game jam as a party; and even my hardcore rpg game designer friends know that at a party you have to sometimes build things ground up to make sure everyone's on the same page or maybe demonstrate it once (maybe on the discord server). it does look like you thought about the philosophy of identity and free will (although i didn't read the referenced book); it's just a shame i didn't have the motivation to dig deeper into what you were saying there because of the instruction barrier and somewhat hastily made gameplay.
but yeah just tried to say you definitely seem experienced and so post-jam updates of this might be nice to see.
