As the first pass of "real" UI, the game can now transition to different screens.
While they are both very sparse and have zero functionality, the game will now launch into a title screen, and then transition to the main game screen after clicking a button.
On the main game screen there's a top bar with a slight gradient and rounded edges, this is the first "art" created for the game. Everything else so far has been from older games of mine, or free assets.
