I've played a bit, but I can not find an option to change the graphics anywhere. can anyone help! Please :D

From the main menu when you start the game, select OPTIONS > Upper left panel has video options. There are only a few basic settings for this game.

You can also reach some of the same options while playing the campaign. Select button in upper left to open pad > select disk icon in lower right > panel on the right that opened out will have video options among a few other options.

In the campaign you can change resolution and full screen or not as well as the camera view angle. At the main menu you can change resolution, full screen or not, and antialiasing.
