To play, use the array keys to move the player(waiter) to left,right,up and down. And you may use space bar to create bullets(hamburger). If the waiter collides with the burger, the game is over.

}For this assignment, I explored the forEach function for the array of bullets and targets and how they collide each other in order to disappear. I also played with the inserting image files into the js file.
