am i aloud to youse block codeing

Why Wouldnt you be? if your using scratch you can use this: https://packager.turbowarp.org/ to convert it to a html file witch you can sumbit on itch

i used scratch for the seajam way back then. its pretty much accepted for jams by now. atleast thats what i think

as i understand, in general, as long as O don't need to download the language to run it, there are no limits on the language you use
