This game should work on most Linux distros with
Xorg installed, I think... Just unpack it, go into
the folder and run it. As for processor power, it
depends on how many ships, bullets and stars you
want to play with. Running with five ships, 500
bullets and 250 stars gives me 340 fps on my
computer. 250 ships, 25000 bullets and 250 stars
at 50 fps.
