Something that makes the game look bad is the plain white background we have at the moment.

When using a background image it will expand to cover all the view.
android:background will stretch the image to make it fit in the view.
We do not want our background image to be stretched in one dimension. We want it to scale uniformly on both axes.

ImageView that covers all the layout with
scaleType set to
centerCrop. This parameter does scale the image ...
