looks great, even tho the mechanics seems very simple which i guess is good since its a mobile game.
Edit:
Oh. battleship mechanics, its nice, with upgrades, standard campaign map and secondary missions, i like it. I hope it will bring an income for you so you can make more games.
You could add In Menu - Add rate game button (and get xx credits) and give some xp/credits when clicked (put var so its no explotaible)
Of course, you probably added a timed, trigger to rate your game, like most do?
Good luck and Good job:)
Thanks for the comment! Glad you like my game!
No, currently I have no Rate Game button, but want to make it and don`t know how to check if user rate my app or not... Or usually its working as just recommendation to user with opening game page in store? Sorry my english ))
And soon I want to make share in facebook button with adding some coins for this.
P.S.: Currently a have only 1 in-game purchase I need to do more with app promotion...
