I would like to introduce you my first android game, is a battleship with cards, and its name is Ocean BattleShip
It's a very special revision of the classic board game battleship with some interesting differences that make it more exciting.

Is absolutely free and it has been made completely by myself.
Try it for twenty minutes, I think you won't be disappointed.
