Default [GAME][2.0.1+]Tic Tac Toe

Hi,

I just wanted to share the first app that I've published on Google Play.
It's a simple game of Noughts and Crosses where you can play against the computer on Easy or Hard settings, or you can play against a friend.

Since this is my first app I'm keen to hear any feedback about any improvements that can be made to the game.

Here's the link: play.google.com/store/apps/details?id=com.gilbert.tictactoe

Thanks
