Hamburgers
For a game made in just a few days this is very entertaining and pretty impressive.
From the game quality to the smooth controls.
Especially the way you designed Osama's ghost(looks cute that I totally forgot what he is actually....:D) and depicted the parody of what a typical American soldier should be. Which is a sleeveless unshaven muscle bound one-hand gun totting trigger happy mindless patriotic maniac. (Yes, you Americans have stereotypes too y'know XP)
Also... Hard mode was hard but not in a bad way. It was pretty fun. It kept my blood flowing and my adrenaline running.
Btw I noticed something. There are a lot less people disliking this flash. Maybe its because we get to kill Osama. But if it is the other way around. What if we exchange the roles as to which we play as ghost Osama and we need to kill that single soldier to win. Yes, it will be the same game but apparently people are narrow-minded and you will be hated to the bone if you do so.... hm...
