I would use this library on ipad and android devices offline only.
I must check the behavior on a real app in android. After a quick test on IOS devices it seems to work but I need more tests.
I had problems only in Chrome offline.
I used Hype only as a HTML widget. the code of the “game” is stored in the scratch.html only.
I made all codes in CSS/JS manually 
It is a simple game inside a widget, however, from this widget you can go to any schene of the hype project.
I used a ( not perfect) javascript and I hope someone can help me to improve the code, please!!
index.html?scene=SceneName?
