There are practical issues with the number of keys simultaneously
pressed. The size of levels and planes might make it very crowded with
more than 2 players. But in principle I would like 4 player support (or
even more ;).

Infinite lives could be shown by just one sprite with an inifinity sign
overlayed. Or without any images as initially proposed by me.
Especially for deathmatch style gameplay I want to see exactly how many
lives are left, even if the fraglimit (and therefore number of lives)

OK, just the way the third level is at the moment.

As with the first two airstrike levels at the moment.

I've just commited something like that to svn. :-)

I can't say how much time I can devote to airstrike at the moment, but
I'll try to do some coding.
