Congratulations, your game got stolen.
[“Literally just a copy”—hit iOS game accused of unauthorized HTML5 code thef] - Ars Technica
I thought of an idea about this…
How about putting a message somewhere in the game saying, something like,
“Please note: this game is not available on the App Store or Google Play as a mobile app. If you see it there, it is PIRATED and I would like your help to report it to them.”
So if the code and assets are copy-pasted, this message would show up and expose the app uploaded as a thief.
