Adding a highscore

It's a no brainer that every game involving a score should have a highscore to challenge the player to beat it. Particularly with my prototypes, where the score is the only way to tell how well the player has done, a highscore is indispensable.

Having said that I've done a bit of research to find out how to save a variable even after the application is closed and then re-opened which would enable to save a highscore.

PlayerPrefs.SetInt("variableName", variableName);

and:

PlayerPrefs.GetInt("variableName");

is what I needed. SetInt remembers a variable whereas GetInt retrieves it.

Here's the updated Square code where I put them:

Now it is only a matter of placing the highscore textfield in the top right corner and leave it there for players to compare with their score.
