DEMONS TO DIAMONDS / Atari / Atari 2600
Well, I see the demons, but not so much the diamonds.
Actually, this game is a pretty crappy fixed-position vertical shooter in the general mold of Space Invaders. Except you have no barriers to hide behind and the jerkiest ship ever, zipping uncontrollably from one side of the screen to the other. You also appear to have the laser weapon from Contra, and have to hold the button down and stay in place to actually get the beam to extend up to where most of the enemies are. Looks like they spent all of about one, maybe two days programming this. Ech.
