I'm thinking of a flyover game, more like the Jets in Combat than
the tank. Constant motion enhances the illusion. You can't put
a lot of stuff on the screen this way but I think I can put enough
stuff on the screen to create the illusion of a fixed landscape.

Rotating the other player is actually trivial. Once you have a way
to rotate the sprite at all, you just subtract your orientation from his
before orienting the sprite. That's the beauty of the co-ordinate
conversion, it magically solves a lot of seemingly intractable problems.
The next build will use 10-bit angles and rotate the other player.
Then, if that's satisfactory, I have some ideas for putting more
stuff on the screen. The usual techniques can't be used since the
rotation ruins any assumptions you might want to make about the
horizontal positioning.
