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?

Interesting idea! Just saying cause I didn’t play it! The artwork looks very good and just think about the high quality SFX on this game! Can be multiplayer to if you think about it! Keep up the good work anyway!
