Thanks for playing! 

The music pausing was elusive to find but it's actually pretty easy! I need to give credit to someone on here named "earthan"

Ctrl F the html file for "pauseTune" You're looking for this piece of code: 

if (soundPlayer) {

    soundPlayer.pauseTune();

and just comment it out by adding two forward slashes before the "pauseTune" part, like so:

if (soundPlayer) {

    //soundPlayer.pauseTune();

But be aware: every time you save your game from the Bitsy maker it will restore this piece of code. So you'll have to comment out the "pauseTune" code in the html file after editing your game in Bitsy, but before your game is played.
