While there isn't much in the way of specifics on the rules, I have faith in this campaign. For one, her kids actually play it! As a fellow game maker, making a game and making a game kids are willing to play, let alone enjoy, are two very different things. In the video she shared in one of her updates, those kids seem genuinely happy! A fun game is a fun game, regardless of if it has shiny art by highly paid/skilled artists or fancy packaging. Heck, I created a card game myself and have yet to try to kickstart it because there are so many cards it'd cost a minimum of almost $30 to professionally produce them, let alone having good art made or shipping it!
Rant aside, this game aims to do what games did when I was growing up - teach children important skills without seeming like homework. And heck, the game is only $15 shipped, which is less than a lot of board games in the store.
Lowest Price Point for Game: $15 (includes a hand-written thank you note and a hug or high five if you ever meet the creator!)
