Hey Billy! Thanks for asking. This isn't a competitive jam so if you just even make a page and submit a buggier build for now and replace it later, that's beyond okay. There will be another 'Murakami Jam' in the near future when I have time to better set it up and support it (and uh... participate myself). There will be a different them and modifier but the rest of the jam will be in the same spirit.
tl;dr Make a page and submit it but feel free to replace the build with a better version when you can. There will be another Murakami Jam but with a different theme/modifier set. :)
