Yeah, I made a print-and-play game
I know that Ludum Dare is more known for digital games, but I really love to try new analogic designs in game jams, so, that is: Perpetual Motion is a solo card game about trying to create the perfect project for a perpetual motion machine, changing the position of the cards creating loops. I'm really proud of making the cards like small blueprints (since I'm not a graphic designer or artist) and i hope you like the game too.
