During gameplay you can go to the pause menu and press new game type in HCRAYERT then press start and you will have lots of ero points do this again and again untill you are happy also if you turn of the the game and take out your memory ard and start it up again it will ask you for your name so type in again that last code HCRAYERT and you will have 44% clear with 1000 points on the start menu but I recomend the first code! have fun!
