Oh and speaking of tablets, does anyone have an Idea USA tablet? It's what I've been using to test on android and the background sometimes vanishes when I try to test via LAN. and on my iPhone, where I'm testing it on IOS, the music doesn't play on LAN.
Could this just be a Wi-Fi hiccup?
— yes, I agree with Scofano, test it on mobile ASAP. I had to totally remake Star Catcher for it to run properly on mobile especially with it being a "Catch stuff as it falls" game.
