All of my apps are available on Android tablets. Mine is a Tesco hudl, easy to use and it didn't cost much. However, my Invaders apps have no explosion sound on the hudl. I think that I know what the problem is and I've fixed it on InvadersAdd but it takes a few hours for Google to accept the changes and then release the updated version. When it does I'll get to work on the other 4 Invaders apps.
