well, the opening screen does show you the controls, and the "play" button are strong implications that you're supposed to interact and play the game. but i admit i couldn't tell when it "started" exactly
a "play" button to press doesn't hint at a game at all, it hints at a movie. you press "play" to play a movie, you press "Start" to start a game. You may argue that those terms can be easily reversed, which may at first glance be a sound argument, but deeper investigation would reveal that you do not play many video games, or have possibly never owned a VCR. This isn't an argument of grammar, this is an argument of tradition, and traditionally we say: ↑↑↓↓←→ ←→ A B SELECT START
