Why wont my game start??

Hello again! I'm sorry for posting so much, but I want to keep updated with the progress I make. So I have my homescreen working. I have my game here in the code too, but why isn't it playing after the homescreen hits the spacebar and it disappears? Any help is very appreciated.
