Yeah and also the game limitation for the jam was “cards as a mechanic” so it seemed more logical for me back then to make everything cards, but when I look back I could have just done a credit card with your stuff.
Remaking it might be a cool challenge. I might be down once I get some free time.
If you read the page fully, you will find out that the theme is indeed shopping, but there is also a “limitation” which NEEDS to be incorporated into the game. In this case “cards as a mechanic”.
