Sorry! It should be working now. Apologies for replying late! I now packed the pck file with the exe file, so there is just one file. You still need to unzip the zip file.
Thanks! Also this was published over a year ago and i was a beginner to godot and music. Its an undertale fangame(i knew nothing about game balance) and personally, I thought the theme was bad at the time!
It doesn't scale to fullscreen or the normal html window fully. You can fix this by going into Godot > project settings>display>window>stretch change mode to canvas_items and change aspect to keep
