Hi!
Yes, you are starting on the number 1. What do you mean exactly by nothing happened?
In the game you are supposed to wait until the screen gets dark and after that you can use the arrow keys to move (up/down/right).
Did you used the web version or the desktop ones? If you are using the web version it's possible that you need to click inside the play area first, because some browsers didn't catch the game window by default.
