A Fish from the Fish Game tutorial is not moving (SOLVED)

So I've been reading the tutorials on TGB, going through the steps, and all was fine, until I reached the first Fish Game tutorial. I've done all the scripting, I've checked and rechecked everything, I searched the forums for solution, I even copied the script from the tutorial itself, but for the life of me I can't make the damn fish to respond to buttons presses. It just kinda hovers there in the middle of the black screen, no matter what I do.
What might I have done wrong?

UPDATE: Sorry, guys, got it solved. It was just a typo in the game.cs. My bad.
