I looked into it, you can't create just random "Chance" without RNG, might as well make a linear path or multiple questionaire, example there is a chance you will roll a 5 on a 6 sided dice, however if it is predestined then no matter how you play, everyone plays the exact same game in same order same steps and get same score, might as well make a visual novel and make a story about some person getting lucky by chance, because that is the only thing that will work for this Jam. Impossible to detach RNG from Chance as they are literally exactly the same thing.
