Very nice! How did you get the music to be specific to each room? Did Bitsy get an added music feature? I have made a few with music but always had to do the trick where you load a YouTube video behind it by altering the HTML code.
there's a hack for it: https://github.com/seleb/bitsy-hacks/blob/master/dist/bitsymuse.js :)
Yeah hacks are the bomb and super useful.
Holy moly. I've gotta make another game now! :P
