Create music for xyz

It currently is really silent while playing the game.

If you are a music/sound creator or (enthusiast), go for it an create music and/or sound effects for the game. We need basically sounds and music for everything.

This is a non-code issue/task. So feel free if you don't exactly know how to contribute by code, to add your music/sounds.

Best place to add them would be in the public folder. We will figure out the final place later on.

Of course you can add them to the game as well if you want/can.
