DIY Gamer arduino error

Hi i just recently started using the DIY gamer kit which comes with an Arduino board, while i tried uploading 'Snake' one of the preinstalled programs onto it, it gave me the error, 'Gamer does not name a type' if you can please tell me how to fix it then please explain it as I am a beginner thanks!

It sounds like you have not installed the libraries. See:-

Failing this we need to see links to what you have and what you are trying to run.
