Fear Spreads V0.02 Update

Did a quick update before the end of the game jam. I learned how to make a simple background music in FamiStudio, along with that I added a way to turn off and on the music in the game(I couldn't figure out how to do it with one button so I used two). I also added a way to exit while still playing the game, without having to lose or win. I don't know if I'll continue to update once the game jam is over, guess we'll see.
