Make-a-Burger!!! When you start you will have a blank bun and patty. You first select the ingredients you want (cheese, onions, tomatoes, lettuce, bacon, and pickles) clicking and dragging your mouse to where you want. Once it is in the right place you press the space bar to keep it there. If you need to you can click it again later and move it. You can have up to three of each ingredient. Make sure its touching the buns of the burger or else it is not apart of the burger! Then press the sauces you want. Then there will be a puddle of it next to the bottle you can click and drag and press the space bar as before.
