It's been great fun, superb graphics and been playing it a few weeks now, paid for a few upgrades etc but tonight the App crashed out and just wont open at all, just gives me a black screen and then crashes back to Phone home screen, dare not uninstall in case I lose all the ships and upgrades? A shame....UPDATE Seems its my Honor Play Phone that just doesn't like the game as runs perfectly on a Samsung Tablet, now also make sure its updated and saved on Google Play so I dont lose progress and upgrades, also better to play on a 10 inch Screen!
