; 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.
