// to control the snake upon getting close to and edge but not crashing — especially
|

// in the highest speed levels. I wanted the highest level to be as fast as I could
|
|
// possibly make the device "run," but on the other hand, I wanted to be friendly
|
|
// and help the player manage that level. Otherwise it might not be fun to play. So
|
|
// I implemented a little delay. A few milliseconds of extra time right before
|
|
// the player crashes, during which she can still change the directions. And if
|

// she does, the game continues.
