I've never seen a printable card game published as a submission. The idea behind the game is original, even though I think the jam is designed to produce interactive software. In any case, the design is there, so nothing is stopping you from digitizing the idea and turning it into a video game.
I really like the aesthetics of the cards and would like to try playing it, but I don't have three other friends to play it with physically.
You've made me want to create a card game video game. Do you have any books or videos to recommend to learn the basics?
