Not sure if this would be the culprit but are you using ogg format for the music? Switching from mp4 to ogg helped me cut the loading time on my game in half.
Thank you for that tip! Yes, I am using ogg music in the game. I'll definitely try out mp4 audio and see if that makes a change.
I meant that I was using mp4 before and switched to ogg to shrink down the size
Ah ok, I understand. Sorry, lack of sleep short circuited my brain there for a bit lol.
