Thanks for the suggestion!
I've always been interested in the QR code format for PICO-8 carts
(as you could probably tell from my interactions with Zep on the Twitter post you referrenced!)
However, until he made the Education Edition, that wasn't really very doable - had forgotten that it could be an option again.
I do already have an (optional) Source Code URL field(s) for submissions, which I suggest ppl use the Education Edition for.
But yeah, maybe a QR code could be cool too.
Lemme think about it - coz it could be cool, but it may also make an already fairly complicated (for) jam MORE complicated! 😅
