This game successfully combines tried-and-true formulas that were successful in other early shooters and ups the ante with brilliant graphics. Each of the enemies are beautifully drawn and consist of multiple vibrant colors. As you progress in the game, you'll encounter different enemies with slightly different characteristics that slightly alter the strategy somewhat. For example, birds which earlier took only one shot to kill now split into two smaller birds when they're first hit, and each of the tiny ones then must be disposed of seperately. This is somewhat reminiscent of Phoenix. In addition, The sheer number of enemies is mind-boggling. You can be playing Demon Attack for hours and you still might not have seen all the different foes that the game has to offer!
All in all, however, it's still the same 'ol same 'ol, but one can't help but appreciate the care and effort put into this game. It doesn't break any new ground, but if god is in the details, Demon Attack could very well have become a religion all its own.
