; The actual game is a 30x30 grid of 8x8 tiles.
; The GS can do 30 wide with 10 tiles to spare.
; The GS can only do 25 tiles tall though. So,
; the screen will be 30 wide pushed to the right-
; most side. The left side will have the score,
; count of lives and the high score. Rather than
; having them at the top, running that info on
; the side will give us more vertical height for
; more on-screen action.
Well, it launches, clears the screen, waits for a key and then quits. But it is a start.
