Good idea, i like it. There is space for improvement, but given the time limit and it being your first game on itch it's pretty good. Be sure to improve it once the jam ends, people like being cats that throw dice xD
Agreed, this could be pretty fun. Just remember, DO NOT modify your submission for the next week unless you are ok with being disqualified from the Jam. I intend to fix the bugs and finish the game loop in mine and re-release in about two weeks, much more polished. (Once rating is over)
