part12studios Are you saying the build worked on iPhone4S but doesn't work on 5S, or did you make a different build for 5S?
Did you minify on export? I was getting a black screen when the js was minified.
Also, I'm getting 30 issues in my build, all Ejecta related. The game did run normally though.
I tested it on iPhone 4 and 5. I never actually tested on the 5S so as far as I know there may well be an issue with the phone, although I doubt it.
