I really wasn't that much impressed by the graphics in this game. At least it was a game that was fairly easy to understand. I am so glad you didn't have to keep on hitting the same button over and over. I was a bit confused by that at first. I thought this would have something to do with the December 21st apocalypse. At least it was something related to an apocalypse.
The scenes on the menu are actually better designed. There could probably be some more variety in the enemies. It's still a pretty well done game. It does seem like this is the first game of its game where it's Santa doing the shooting. You could make his weapons more Christmas oriented.
