This is a rule in jams like Ludum Dare, etc.

Just needed clarification

i think so

More fun that way. Also, it really helps to find bottlenecks in your game creation process.

It would be more authentic to make the assets yourself, but you can base yourself on any third-party sprites as inspiration if you want

You don't need to make the music yourself, in case you don't know how to make it.

Thanks all for the reply. Just returned from school. So ready for this jam.
