Since it seems like spirit of this contest is taking a constraint-based fantasy game development console and further constraining the developer I was wondering if it wouldn't be interesting to add another category where the game must be submitted as a QR code. And I don't mean QR code URL link that redirects you to someone's webpage they exported from Pico-8 but a QR code that redirects people to the webrunner and where the entire program is stored as a URL parameter.
Here is a post with a bit more information of what I am suggesting and why QR code carts are kind of neat. And they scan great (and run great) from mobile phones.
