The Rules said you can use any Game engine so i guess you can if you rly want to But they might not accept Scratch as a game engine so idk

im gonna use scratch if i join

I guess you can but I suggest using a bigger engine such as unity

Plus you probably wont find many devs to continue your scratch game

If I do the game jam, I'll be using Scratch/Turbowarp since my computer ain't that good

I would assume not since scratch is more of a platform then a game engine.

I think you probably could, but in my experience scratch games aren’t that great because for some reason you can only get 1 input at a time, meaning you couldn’t even do the classic run and jump
