Yeah I really did want to add background music but I have no skills in audio. I know I could find some free assets online which I have done in past game jams but couldn't find something. This game I made everything myself, well aside from the font I guess. The little bit of sound effects I made myself and it was difficult enough. I even spent a while trying to make my own "You got mail" soundbite but was never happy with it so settle with the sound.
I did consider the idea of pop ups making sounds. I thought it could fit into the last wild card of "silence" where you want to silence the popups. And I would have added an app that could silence everything. I think it might have been too annoying to players but also just kind of ran out of time with burnout near the end of the jam.
