Clever thinking, I wouldn't have thought of expanding the spacing to 12
pixels, and I would have thought that that would make the formation too
wide and not have enough space to move laterally, which is a concern in
your demo, although minor, and certainly can't be increased anyway. You
can also use the full 8-pixel width of the sprites easily now, although
you haven't for all the invaders. 60 bytes of RAM is a bit worrisome, but
all that counts is if everything fits when all is said and done :)

Unfortunately I'm at college and my Atari isn't, as I'd love to see this
run :(
