UFO Odyssey - One Button Ver.

I chose to work with a game I made last semester called UFO Odyssey. It is a 2D space shooter game where you play as a UFO to fight through swarms of human astronauts. 

Originally, the game was played with a keyboard with control options, such as W, A, S, and D for movement and the space key to shoot laser beams. In order to fit it into the parameters of this project, I modified the movement controls and changed shooting to auto-fire. I changed the Arduino code so that the button will input "D" when pressed and "A" when not pressed. As a result, the player can control the UFO with only one button for horizontal movements.
