If you ever get a real 2600, perhaps you should consider slapping around
the HMOVE variables to see if you can get something similar to the Cosmic
Ark stars, but more line-like. Problem with that is, people without
Superchargers will be very mad at you, and there's a chance it can't
be done.

Using both players for the monster gives you a good 16 bits to work with.
By careful designing around the middle, you can even shrink it and expand
it by one or two pixels without changing graphics, just by making them
overlap.

Sky Jinks had a cool effect where the clouds actually cast a shadow on the
plane. Perhaps when flying above clouds, the plane can cast a shadow?
Not knowing the nature of either the clouds or the shadow, I don't know
if this is possible.
