Haha agreed, hopefully I'll return to the project at some point and add it :)
What kind of music do you imagine when playing? I was thinking some spooky ambient noise, but it now it doesn't really feel like it fits with the pace of the game aha
I suggest an upbeat music, since your game has an arcade feel, but please mix it well, which means don't make it too loud, and I suggest you make the sound effects louder. These are just advice :)
