An exelent game
As others have said, it is hard. However, it is a most exelent game. The idea is funny enough, and adding the music and background gunfire was good. I enjoyed using both the carbine and the Tomson machine gun. The gun animation was top-knotch. Some people have said that the Nazi base/castle/etc. wasn't drawn too well, but I think it looks good that way. I hope you make more fun games that combine millitary and arcade.
SUGGESTIONS: Some more guns would be fun, and moving the crouch/stand up buttons over.
P.S.- I would like to work on a game with you sometime. Email me if you want or something. I'd realy like to help out on your next great game.
