Thank you so much. Yes music ;) No clue how to create music but I definitely want to try to learn how to do a simple audio loop. It was one purpose to come out of my comfort zone by creating this game and do more than just coding for once. Could manage to do some simple 2 bit graphics and cheated a bit on sounds in the end by using https://github.com/mneubrand/jsfxr to auto generate them. But I really want to play with sounds and music soon. At least I want to have some clue what those creative people do :)
