Oh my goat: Originally, I just wanted to look at your pitch, but then I read half of the rules by accident - the For the MG chapter finally snapped me out of it, since these chapters usually make me stop instinctually. Good job! :) I particularly liked how physical the curse ideas felt. They are easy to imagine and I could see people actually represent them at a more LARP-y gaming table without having to do too much effort.
I will definitely add this to the pile of things to try (once our group can meet in person again).
