This rules! I love this solitaire variant, and I'm excited for future updates!
I'd love to see other modes from the Zachtronics Solitaire Collection make their way to Playdate too.
Thanks for the feedback.
This is the main variant I keep coming back to, but maybe some day I'll get to some other variants as well.
I'm currently play testing the 12-set mode. It works, and has a nice difficulty ramp. But actually designing the hanafuda cards though is more work than I had expected (in Hanafuda each image in a set is different, so it's 48 drawings).
