Thanks for sourcing the error! I'm not well-versed in the technicalities to be honest haha, but I'll try to find a solution! Thank you for playing the game even without music ^^
unfortunately I have no music either (Chrome). I had a similar problem when I first put Pawprints up where not everyone was able to access the music and had to change the hosting. I can't remember who I finally ended up getting a working hosting with in the end. I'll find out and let you know.
