Beautiful game. Not sure if it's from my side but there is no BGM. Would be a best fit for 'Child of Light' style soundtrack

Ok, I think we figured out the sound. The game can be loaded and played without the window being focused. So if you Full Screen the window, it should ensure focus, and the sound should play. If this doesn't work, I'd love to know which browser you are using.
I actually listened to the Child of Light soundtrack quite a bit while programming for it :)
