well technically scratch is a game engine in a website so no need to download stuff. Unlike roblox with scratch you start from scratch (no physics, character movement etc) so as i understand it my submission should be fine
Great! :) You should still check with someone from the game jam to be sure (they seem to enforce the rules rather strictly…), just to know as early as possible. Good luck!
yes i am going to contact the administrators or such of the game jam, and if it gets disqualified i at least had fun coding this and knowing people like it
