Game within a different fla

So I made a movie, then I made a game to go along with it. I made the game in a seperate FLA. After I was done making the game, I went through to make sure I never used _root. I hadn’t (I think I’m pretty sure, I’ve checked a couple times.) I basically copied all four frames of my game and put them in a movieclip in the original movie. However, when I exported this, the game…well, you can see for yourself. It just…doesn’t work.

Here’s the FLA of the game and movie:

Here’s the SWF of the game and movie:

And just to prove that the game itself did work, here’s the SWF of the game:

What did I do wrong, how can I fix it?
