For the first part of my game, I have used parts of the retro lab to develop it. I changed to screen size and layout to be wider than the retro lab. I have also incorportated the player to move up, down, to the right, and to the left of the screen. The next part of my game is going to add "aestroids" that was in the retro lab but I will adjust bits of it to create it my own!!
