My newest game was for WizJam, and it's still very much a work in progress. It's called cementville. It's a TTRPG for players and a GM about witches and wizards living poor in the rust belt, and how casting and magical goals are effected by poverty. It is a diceless system. Instead of rolling to resolve moves or spells, you instead try to flip a card from at least a foot up to hit a target of the DMs choice. Depending on where and how the cards land, spells and actions have different resolutions. It's made to be played as an ongoing campaign, but could easily be a one shot as well. Let me know what you think!
