When deploying a build to Itch.io I get the following error on Chrome browsers: “The AudioContext was not allowed to start. It must be resumed (or created) from a user gesture event handler. https://goo.gl/7K7WLu”
I think the way the pixelbox library initializes the AudioContext needs updated to resolve this.
