Hello!
This will be my first entry ever into a game jam and I'm very excited! I do have a (hopefully) simple to answer question. Are assets that I have made previously (song snippets, pixel art, etc.) allowed to be used? I know the rules state that:

" Your game must be mostly original. Making everything from scratch is not mandatory, but if you do you get to be extra proud of yourself at the end!"

The assets are original, but an amount of it will have been created/prepared beforehand. Is this allowed?

Thanks!
Matt
