I modified one tutorial a little bit and changed it to full screen app like this:
On iOS I could manage to add it as an app by 'Add to Home Screen' in Safari. It runs fine (ignoring the control). But the problem is that in the middle of the game if I switch to another app and then back to it, it will always reload, thus losing the current progress of the game. Same symptom happens on Android as well.
Is there a way to avoid reloading the game on resume? The .capx file is here for reference:
Appreciate your help in advance.
