It's a massive update of the older version of Kill Hamas Alpha. Now it's Beta, I don't think that I am going to finish it so, let's call that game just a survival.
Sometimes there is "ghost enemy" you can see it, but can't shoot it, and he can't touch you ether. He just passes you and the enemy detector thinks that the stage isn't clean yet, and blocks the ready button. To fix that, in few seconds there is a "Stuck?" button popping up, press it, and your ready to continue.
Leave your high score on the reviews, with a comment should I continue working on it or not.
