Atari's Tempest

Tempest is a creative game.  You are some kind of ship or gun that is shooting at these x-things that are shooting back at you.  It takes some skill to keep up with the changing shape and speed of the game.  It is very colorful and is mostly simple lines and shapes moving across the screen.

I find this game to be very captivating.  If I saw this game in an arcade I would have a hard time not feeding it all of my coins.  It has lots of levels in many shapes.  There are even a few sides that are hard to see until you move down them.
